Biggles Flies East Part 9

Biggles started. 'You want me to lead the bombers, sir?' he e.j.a.c.u.l.a.t.ed.

'Why not? It is a trifle irregular, I know, and Ober-leutnant* Kranz, who is commanding the Staffel in Mayer's absence, may feel hurt about it, but as you know where the place is you will be able to go straight to it. Kranz can still be in command, but you could show the way and take charge of the operation just while you were over the British lines. Is that quite clear?

'Quite, sir,' replied Biggles, whose head was in a whirl at this fresh complication. The idea that he might have to accompany a raid, much less lead one, had not occurred to him.

Each machine will carry two heavy bombs,' continued the Count, 'and one machine will, of course, take a camera so that we can study the layout of the aerodrome at our leisure as well as see if the bombs do any damage.'

I'll take the camera if you like, sir,' volunteered Biggles, who thought he might as well be hung for a sheep as a lamb.

'That would be excellent. Then I'll leave it to you to fix up the details with Kranz. Good luck!'

Biggles saluted and withdrew with mixed feelings, for the fact that the dummy aerodrome lure had worked out well was rather overshadowed by the part that he had been detailed to play, and he realized that during the next two hours there was a strong possibility that he would be shot down by his own countrymen; and he did not overlook the fact that in the event of his formation being attacked, he might find it difficult not to put up some sort of fight, or pretence of fighting, yet he had no desire to be responsible for the death of a British pilot.

I shall have to hope for the best, that's all there is * Flying Officer in the German Air Force to it,' he thought as he walked along to the hangars where the bustle indicated that preparations for the raid were going forward.

Half an hour later the six machines left the ground in V-formation with Biggles flying at the spear-head, and climbed steeply for alt.i.tude. For nearly an hour they roared upwards on a broad zigzag course before heading straight for the lines. They crossed over through a thin and futile archie barrage, and then raced on full throttle towards the now visible aerodrome.

Biggles, who, of course, had not seen it before, was completely amused at the realism of the bait. It was complete in every detail, even to some machines standing on the tarmac.

There was no wind so it was unneccesary to turn in order to deliver the attack, and the first six bombs sailed down. But to Biggles' disgust they nearly all went wide; one only fell on the aerodrome and none touched any of the buildings. He had hoped to take a really thrilling photograph back to the Count, showing at least one hangar in flames.

The six machines turned slowly in a wide circle in order not to lose formation, and then returning from the opposite direction, laid their remaining eggs, that is, all except Biggles, who was determined to score a hit, for now that he was actually engaged in the task, the idea of bombing a British aerodrome amused him.

This time the aim was better. Two bombs fell on the aerodrome, and one in the end hangar, but still he was not satisfied, so he dived out of formation, losing height as quickly as possible, and turning again towards the aerodrome, took the centre buildings in his bomb-sight and pulled the toggle. For a few seconds the bomb diminished in size in a remarkable manner as it plunged earthwards, and then a pillar of smoke and flame leapt high into the air. It was a direct hit. He had his camera over the side in an instant, but the movement might almost have been a signal, for he had only taken two photographs when such a tornado of archie burst around him that he dropped the instrument quickly on to the floor of the c.o.c.kpit and pulled up his nose to rejoin the formation.

The other five machines were in no better case, and it seemed to him as he raced through a sea of smoke and flame that every anti-aircraft gun on the British front had been concentrated on the spot.

Of course they have: what a fool I am,' he swore. 'Raymond would know that I'd give the Huns the position of the aerodrome, in which case it would be certain that sooner or later a formation of Boche bombers would come over. He could easily get the guns together without disclosing anything about my part of the business. My gosh! I ought to have thought of that.' He flinched as a piece of metal tore through his wing and 'made the machine vibrate from nose to rudder. A sh.e.l.l burst under his tail, and his observer, a youth named Bronveld, made desperate signals to him to get out of the vicinity as soon as possible.

He needed no urging. His one idea at that moment was to remove himself with the utmost possible speed from the hornets' nest he had stirred up, and all the time he was wondering what the other pilots would say, and more important still, what the Count would say when they got back-if they did-for the whole exploit bore a suspicious likeness to a well-laid trap. 'No,' he reasoned, as he side-slipped away from a well-placed bracket* that blossomed out in front of him, 'they can't blame me very well, for after all, I'm in the show myself, and no one is fool enough to step into a * Bursting sh.e.l.ls on both sides of a target trap they have themselves set. In fact, it begins to look almost as if it were a good thing that I came on the show, otherwise-'

His high speed soliloquy was cut short by an explosion under his wing tip that nearly turned him upside down. He tried the controls with frantic haste, and breathed a prayer of thankfulness when he found that they were still functioning, but a long strip of fabric that trailed aft from his lower starboard plane made him feel uneasy. One of the other machines suddenly dipped its nose and began gliding down; he noted that its propeller had stopped, but thought it might just manage to reach the German lines that now loomed up ahead of them.

The formation, which had become badly scattered in the barrage, now began to re-form, and he had just taken his place in the lead when, glancing forward through the centre-section, he saw something that set his finger-tips tingling. Cutting across their front on a course that would effectually cut them off from the German lines were two squadrons of aeroplanes that needed no second look to identify them. One squadron, approaching from the west, was composed of eight Sopwith Pups with a solitary Camel hanging on its flank; the other, which was coming up from the east, comprised six Bristol Fighters.

Biggles eyed the Camel with a strange expression on his face, for the circ.u.mstances were so-well, he didn't know quite what to call them, for never before had he seen comedy and imminent tragedy so hopelessly intermingled. 'I'd bet a month's pay to a piastre that Algy has a smack at me first; he always does like taking on the leader,' he muttered. 'And I'd have won,' he went on bitterly, as the Camel pulled up in a steep zoom, half-rolled, and then whirled round for the attack with its nose pointing down at Biggles' Halberstadt.

For once Biggles was nonplussed and a thousand ideas flashed through his brain, only to be abandoned instantly as he realized their uselessness. He glanced back over his shoulder and saw. Bronveld crouching over his gun, waiting for the Camel to come within range. The lad's face was grim and set, but his hands were steady, and Biggles felt a thrill of apprehension. 'That kid's going to put up a good fight,' he thought anxiously. '

And from the way Algy is handling that Camel it looks to me as if the young fool stands a good chance of stopping a packet of Spandau bullets. He must be crazy to come down on top of us like that, straight over our rear gun.'

Then something like panic seized him as he visualized the unthinkable picture of his gunner killing Algy, or conversely, Algy's feelings when he found he had shot down his best friend. Whatever else happened, that must be avoided at all costs. Better to betray himself and be shot by the Huns than that should happen. 'At least I can let him know it's me,' he thought as, white-faced, he reached for his signal pistol, slipped in a red cartridge, and sent a streak of scarlet fire blazing across the nose of the diving Camel.

But to his horror the pilot paid no attention to it, although, as if actuated by a common motive, the four remaining Halberstadts banked hard to the right and closed in on him.

More with the object of avoiding a collision, he swung round in a fairly steep bank, and the other machines fell in line behind him.

The movement disconcerted the British pilots, who now found themselves facing an ever-circling ring from which guns spat every time they tried to approach, and while they were still milling round them in indecision, Biggles darted out of the circle at a tangent and raced, nose down, for home. By the time the Pups and Bristols realized what had happened the other Halberstadts had followed on his tail and had established a clear lead, which they were able to keep until they were well inside their own territory. The danger was averted.

Biggles brushed his hand across his forehead. 'Phew! that was quite enough of that,' he muttered, as he looked back over his shoulder, and then stiffened with horror at the sight that met his eyes. The British machines, with the exception of one, had turned back, but the Camel, by reason of its superior speed, had continued the chase and had caught them.

What was worse, its pilot was evidently still determined to strike at the leader of the Hun formation, and was roaring down in a final effort. As it came within range jets of orange flame darted from the muzzles of the guns on its engine cowling, and at the same moment, Bronveld, who was alive to the danger and crouching low behind his Parabellum gun, pulled the trigger. His aim was true. Biggles saw the tracer leap across the intervening s.p.a.ce in a straight line that ended at the whirling engine of the British machine. Something stung his shoulder but he hardly felt it, for his eyes were fixed on the Camel in a kind of fascinated horror. Its nose had jerked up in a vertical zoom; for a moment it hung in s.p.a.ce with its propeller threshing the air uselessly; then it turned slowly over on to its back and plunged earthward.

In a state of mental paralysis Biggles watched it hurtling through s.p.a.ce. He couldn't think. He couldn't act. He could only stare ashen-faced at the spinning machine. He saw a wing break off, and the fuselage with its human cargo drop like a cannon-ball; then he turned away. He shifted his gaze to Bronveld, who was clapping his hands jubilantly. As their eyes met the German showed his teeth in a victorious smile and turned his thumbs upwards, a signal that means the same thing the world over. Biggles could not find it in his heart to blame him, for it was the boy's first victory, and once, long ago, he had behaved in exactly the same way; only that time the spinning machine had black crosses on its wings, not red, white, and blue circles.

He turned back to his own c.o.c.kpit feeling as if he had turned into a block of stone.

Something seemed to have died inside him, leaving in its place only a bitter hatred of the war and everything connected with it. He ground his teeth under the emotion that shook him like a leaf, while in his mind hammered a single thought, algy has gone west . . .

Algy has gone west.' The wind seemed to howl it in the wires, and the deep-throated Mercedes engine purred it in a monotonous vibrating drone.

Through a shimmering atmosphere of unreality he saw the aerodrome at Zabala loom up, and automatically throttled back to land. His actions were purely instinctive as he flattened out and taxied slowly up to the hangars. The Count, von Stalhein, and several other officers were standing on the tarmac waiting, but none of them meant anything to him now. He no longer feared von Stalhein. He no longer cared a fig if he was suspected, arrested, or even shot.

He switched off, climbed stiffly to the ground, and walked slowly towards the spot upon which the others were converging. He could hear a babel of voices around him, German voices, and a wave of hatred swept over him. What was happening? He hardly knew. He became aware that Bronveld was tapping him on the back while he spoke rapidly to Faubourg. They were all laughing, talking over the battle, and a strange feeling swept over Biggles that he had seen it all before. Where had he seen the same thing? Suddenly he knew. The scene was precisely that which occurred on any British aerodrome after a raid; only the uniforms and the machines with the sinister Maltese crosses were different. As in a dream he heard the Count speaking.

'Splendid,' he was saying, 'splendid. Kranz is full of praise for the way you handled a nasty situation. Your firing of the red signal to form circle when you did, he says, saved the whole formation. And that last bomb of yours, and the way you left the formation to make sure of a hit, was brilliant. Your recommendation for the Iron Cross shall go off today. And Bronveld has shot down a Camel. We knew that before you got home; it fell in our lines and the artillery rang up to say they are sending the body here for burial. We will see that it is done properly, as we always do, because we know the British do the same for us. But what's this? Why! you're wounded, man.' He pointed to Biggles'

shoulder, where a nasty-looking red stain was slowly spreading round a jagged tear in his overalls.

Oh, that.' Biggles laughed, a hard, unpleasant sound. 'That's nothing. I hardly noticed it.

The Camel fired the shot,' he added, wishing that it had gone through his head instead of his shoulder.

'While you were holding your machine steady so that Bronveld could shoot,' observed the Count. 'That is the sort of courage that will serve the Vaterland. * But go and get your shoulder attended to and make out your reports, all of you. I am looking forward to seeing the photographs.'

Biggles removed his flying cap and goggles and walked towards the Medical Officer's tent. He was * The Fatherland: Germany conscious that von Stalhein was watching him with the same puzzled expression that he had worn after the Mayer exploit. 'He doesn't know what to make of me,' he thought. '

Well, a fat lot I care what he thinks. I'll fly over to Raymond to-morrow, and throw my hand in; in future I'm flying in my own uniform, in France, or not at all. I've had enough of this dirty game and I never want to see a palm tree again.'

The wound, which was little more than a graze, was washed and bandaged by the elderly, good-natured German doctor, after which he went to his room and threw himself on his bed. The sun was sinking like a fiery orange ball in a crimson sky that merged into purple overhead, and threw a lurid glow on the hangars and the sentinel-like palms. It flooded into his room and bathed his bed, his uniform, and his tired face in a blood-red sheen.

For a long time he lay quite still, trying to think, trying to adjust himself to the new state of things, but in vain. His most poignant thought, the thing that worried him most, was the fact that he had been responsible for Algy's death in the first place by causing him to be posted from France to the land of the Israelites. That Algy might have been killed if he had remained in France did not occur to him. 'But there, what does it matter? What does anything matter? The lad's gone topsides, and that's the end of it,' he thought, as he rose wearily. He washed, and was drying his face, when an unusual sound took him to the window. A tender had stopped and half a dozen grey-coated soldiers in the uniform of the German Field Artillery, under the supervision of a Flying Corps officer, were unloading something. It was a long slim object shrouded in a dark blanket.

He watched with an expressionless face, for he was past feeling anything. It was all a part of the scheme, the moving of the relentless finger of Fate that had lain over Palestine like a blight for nearly two thousand years and left a trail of death in its wake. He watched the soldiers carry the body into the tent that had been set aside as a temporary mortuary. He saw them come out, close the flap behind them, salute, and return to the tender, which, with a grinding of gears, moved slowly across the sand and disappeared from sight. It was like watching a scene in a play.

Then, moved by some impulse, he picked up his cap, left the room, and strode firmly towards the tent. 'I might as well say good-bye to the lad,' he thought, with his nostrils quivering. He threw aside the flap, entered, and stood in dumb misery at the end of the camp bed on which the pitiful object rested. Slowly and with a hand that shook, he lifted the end of the blanket-and looked.

How long he stood there he never knew. Time seemed to stand still. The deathly hush that falls over the desert at the approach of twilight had fallen; somewhere in the desert a sand-cricket was chirping. That was all. And still he stared-and stared.

At last, with a movement that was almost convulsive, he replaced the blanket, stepped back, and leaned against the tent-pole while he fought back an hysterical desire to laugh aloud-for the face was not Algy's. It was that of a middle-aged man in the uniform of an infantry regiment, with pilot's wings sewn on his tunic above the white and violet ribbon of the Military Cross. It was quite peaceful. A tiny blue hole above the left eyebrow showed where life had fled, leaving a faint smile of surprise on the countenance, so suddenly had the end come.

Biggles pulled himself together with a stupendous effort and walked reverently from the presence of Death. With his teeth clenched, he hurried back to his room and flung himself face downwards on his bed, laughing and sobbing in turn. He did not hear the door open quietly to admit an orderly with tea on a tray, who, when his startled eyes fell on his superior officer, withdrew quickly and returned to the camp kitchen.

'Karl,' he called to the cook, 'Brunow's finished-nerve's gone to bits. Funny how all these flyers go the same in the end. Well, I don't care as long as they'll let me keep my feet on the ground.'

Chapter 15.

Ordeal by Night The German orderly, although he had good reason for thinking that 'Brunow's nerves had gone to bits', was far from right. Biggles' nerves were unimpaired, although it must be admitted that he had been badly shaken by the belief that Algy had been killed, but after the first reaction had spent itself the knowledge that the whole thing had been nothing more than a bad dream was such a relief that he prepared to resume his work with a greater determination than before. Lying propped up on his pillow, he reviewed the events of the day which, taking things all round, might have panned out a good deal worse. Hess had gone west, and he had no regrets on that score. 'Yes, taking it all round I've been pretty lucky to-day,' he mused, which was not strictly true, for such successes as he had achieved had been due more to clear thinking and ability than to good fortune.

His only stroke of what could be regarded as luck was the firing of the red signal light which had saved the formation, thereby putting up his reputation with the Staffel, for when he had fired it he had not the remotest idea that it was the German signal to 'form circle', a fact that he could only a.s.sume was the case from what followed.

By dinner-time he was normal again but eager to see the end of his masquerade in order that he might return to normal duties. So deep-rooted was this longing that he was prepared to take almost any chance, regardless of risks, in order to expedite the conclusion of the affair.

Certain vital facts he had already grasped; of others, a shrewd suspicion was rapidly forming in his mind, and he only needed confirmation of them to send him to British headquarters and place his knowledge at the disposal of those who would know best how to act upon it.

It was with a determination born of these thoughts that he decided during dinner to pursue his quest in a manner which inwardly appalled him, but which, he thought, if successful could hardly fail to produce results. The idea came to him on the spur of the moment when he heard a machine taxi out across the aerodrome. Subconsciously he waited, expecting to hear it take off, but when it did not he knew-guessed would perhaps be a better word-that it was standing on the far side of the aerodrome waiting for a pa.s.senger about whose ident.i.ty there was no doubt in his mind. And when a few minutes later von Stalhein left his chair, and after a whispered conversation with the Count, went out of the room, he fancied that he knew what was about to take place.

He would have liked to follow at once in order to watch von Stanhein, but that was out of the question, for it was a matter of etiquette that until the Count rose and led the way to the ante-room, no one could leave his place without asking his permission, and then a very good excuse would be demanded.

So he sat where he was, sipping his coffee, but listening for the sound that would denote von Stalhein's departure for the British lines; and he had not long to wait. Within a few minutes there came the distant roar of an aero engine; it swelled to a deep crescendo and then died away in the distance. 'There he goes,' he thought. 'If I could only be at the other end when he lands I might learn something.'

Now that his mind was made up on a course of action he fidgeted with impatience for the meal to end, and when at length the Count got up, the signal for a general move, he followed the others through to the ante-room with a light-heartedness which sprang, not from antic.i.p.ation of the self-imposed undertaking before him, but from relief of knowing that the time had come to begin. He hung about conspicuously for a little while, turning over the pages of a magazine, and then satisfied that everyone was settling down for a quiet evening, he left the room and walked unhurriedly to his quarters, where he changed his regulation boots for a pair of the canvas shoes that most of the officers wore when off duty, and slipped an electric torch into his pocket. This done, he strolled towards the tarmac. He did not go as far as the front of the hangars, but turned to the left behind them and moved along in the direction of the fort. The building was in darkness, but knowing that a sentry would be on door duty, he kept to the rear, and then worked his way down the side until he stood under the window where, a few nights before, he had seen von Stalhein writing.

With his heart thumping in spite of his outward calm, he took a swift glance around to make sure that he was not being watched, and then, reaching for the window-sill, drew himself up until he could throw a leg across the wooden frame. The other followed, and he slipped quietly inside.

After the bright starlight outside he could see nothing at first, but by waiting a minute or two for his eyes to become accustomed to the darkness, he could just make out the general outlines of the furniture. He crossed swiftly to the door, and tried it, but as he expected, it was locked, so he went over to the writing-desk upon which a number of doc.u.ments were lying, but they were, of course, written in German, so he did not touch them. In any case he was not particularly concerned with them. Working swiftly but quietly, he made a complete inspection of the room, and then turned to the tall wardrobe which stood against the far wall. He opened it, and shielding the torch with his cupped hands, he flashed it on the interior, when he heard a sound that brought him round with a start although not particularly alarmed, for it came from the direction of the window. It seemed to be a soft sc.r.a.ping noise, a rustling, as if a large bird had settled on the ledge.

Bending forward, he could just make out two dark objects that moved along the window-sill with a kind of groping movement. For a moment he could not make out what they were, and then he understood. They were hands. Some one was coming in through the window.

Now even in the flash of time that remained for him to think, he knew there were only two courses open to him. One was to step forward and confront the marauder, who, by his clandestine method of entry, obviously had no more right in the room than he had, and the other was to hide. Of the two the latter found more favour, for the very last thing he wanted was the hullabaloo that might conceivably take place if he allowed himself to be seen. So he stepped back, squeezed himself into the wardrobe, and pulled the door nearly shut behind him just as a man's head appeared in the square of star-spangled deep blue that marked the position of the window. Even in the uncertain light a single glance was sufficient to show that it was not a European, for the dark-bearded face was surmounted by a turban. As silent as a shadow, the Arab swung his legs and body over the sill with the feline grace of a panther, and stood in a tense att.i.tude, listening, precisely as Biggles had done a few minutes before. Then, still without making a sound, he glided forward into the room.

For one ghastly moment Biggles thought he was coming straight to the wardrobe, and he had already braced himself for the shock of meeting when the man stepped aside and disappeared from his limited line of vision. For a moment he wondered if he had gone to the electric light switch with the object of turning it on, but the half-expected click did not come. Nor did the man reappear. Nothing happened. All was as silent as the grave. A minute pa.s.sed, and another, and still nothing happened.

Then began a period of time which to Biggles' keyed-up nerves seemed like eternity; but still nothing happened. Where was the man? What was he doing? Was he still in the room? Could it be possible that he had slipped out of the window again without being noticed? No, that was quite impossible. Had he in some way opened the door and gone out into the corridor? Definitely no; in such an aching silence, for any one to attempt to turn the handle, much less the lock, without being heard, was manifestly absurd. What, then, was happening?

Such were Biggles' thoughts as he stood in his stuffy hiding-place fighting to steady his palpitating heart. Another ten minutes pa.s.sed slowly and he began to wonder if there had been a man at all. Could the whole thing have been a vision conjured up by his already overtaxed nerves? The tension became electric in its intensity, and he knew he could not stand the strain much longer. Could he rush to the window, throw himself through, and bolt before the man in the room had recovered from the shock of discovering that he was not alone? He thought he could, but it was a desperate expedient that he preferred not to undertake until it became vitally necessary.

Then at last the silence was broken, broken by a sound which, as it reached his ears, seemed to turn his blood to ice. He had heard it many times before, and it never failed to fill him with a vague dread, but in his present position it literally paralysed him. It was the slow dragging gait of a lame man, and it was coming down the corridor. Then it stopped and there was a faint tap, tap, and Biggles knew that von Stalhein was propping his stick against the wall while he felt for his keys. In his agitated imagination he could see him, follow his every action, and the grinding of the key in the lock sounded like the first laborious move of a piece of badly oiled machinery. Slowly the door creaked open on its hinges. There was a sharp click, a blaze of blinding light, and von Stalhein stepped into the room.

At that moment the Arab sprang. Biggles saw him streak across the room with a brown arm upraised, and caught the flash of steel. But if the Arab hoped to catch the German unaware, he was doomed to disappointment.

Never in his life before had Biggles seen anything quite so swift as that which followed.

With a lithe movement that would have been miraculous even for an athlete, von Stalhein dived forward with a galvanic jerk; the top part of his body twisted, and the curved blade that was aimed at his throat missed his shoulder by what must have been literally a hair's breadth. His sticks crashed to the floor. All the force of the Arab's arm must have been behind the blow, for his lunge carried him beyond the German, who was round in a flash. His hand darted to his hip pocket, but before he could draw the weapon he obviously kept there the Arab was on him again, and he was compelled to use both hands to fight off his attack.

Again the Arab sprang, and as his right arm flashed down von Stalhein caught it with his left, while his right groped through the folds of his flowing burnous for the brown throat.

In that position they remained while Biggles could have counted ten, looking for all the world like a piece of magnificent statuary. Neither of them spoke; only the swift intake of breath revealed the quivering energy that was being expended by each of them to hold the other off. Then the tableau snapped into lightning-like activity.

Biggles couldn't see just what happened. All he knew was that the knife crashed to the floor; at the same moment the Arab tore himself free and flung himself at the window.

He went through it like a greyhound, but, even so, the German was faster. His right hand flashed down and came up gripping a squat automatic, and at the precise moment that the Arab disappeared from sight a spurt of yellow flame streaked across the room. Von Stalhein was at the window before the crash of the report had died away; with the agility of an eel he threw his legs across the sill and sprang downward out of sight.

Biggles seized his opportunity; he stepped out of the wardrobe, closed it behind him, darted to the door and sped down the corridor. He hesitated as he reached the main entrance, eyes seeking the sentry, but no one was in sight, so he ran out and took refuge behind the nearest hangar. At that stage he would have asked nothing more than to be allowed to return to his room, but he saw figures hurrying towards the fort from the Mess, so he turned about and ran back as if he had heard the report of the shot and was anxious to know the cause. Doors were banging inside and voices were calling; he paid no attention to them but ran round the side of the building, and then pulled up with a jerk as he almost collided with von Stalhein and the door sentry, who were bending over a rec.u.mbent figure on the ground. He saw that it was the Arab.

'Good gracious, von Stalhein,' he exclaimed, 'what's happened? What was that shot?'

'Nothing very much,' replied the German coolly. 'Fellow tried to knife me, that's all. One of the sheikhs who was on the raid the other night; the poor fools are blaming me because the thing went wrong. By the way, where have you just sprung from?'

It was on the tip of Biggles' tongue to say 'from my room', but something warned him to be careful. Instead, 'I was admiring the night from the tarmac,' he smiled; 'I can't sit indoors this weather. Why?'

'Because I looked into your room just now to have a word with you, and you weren't there,' was the casual reply.

Biggles caught his breath as he realized how nearly he had made a blunder. 'What did you want me for?' he inquired.

Oh, merely a job the Count had in mind, but don't worry about it now; I'll see you in the morning. I shall have to stay and see this mess cleared up, confound it.' Von Stalhein touched the Arab with the toe of his patent leather shoe.

all right. Then I think I'll get to bed,' returned Biggles, as several officers and mechanics joined the party.

Safely out of sight round the corner of a hangar he mopped his face with a handkerchief.

'My gosh,' he muttered, 'this business is nothing but one shock after another. "Where have you just sprung from?" he asked. I felt like saying, "And where the d.i.c.kens have you come from?" He couldn't have been in that machine that took off, after all; I'm beginning to take too much for granted, which doesn't pay, evidently, at this game. And so he's got a job for me in the morning, eh? Well, with any luck I shan't be taking on many more jobs in this part of the world, I hope.'

Chapter 16.

Checked The next morning he was awakened by his batman* bringing early morning tea. He got out of bed, lit a cigarette, and sat by the open window while he considered the results of his investigations. How far had he progressed? How much had he learned about El Shereef, the German super-spy? Had he arrived at a stage when, figuratively speaking, he could lay his cards on Major Raymond's desk and ask to be posted back to his old squadron, leaving the Intelligence people to do the rest? No, he decided regretfully, he had not. He had learned something, enough perhaps to end von Stalhein's activities, but that was not enough, for while the British Intelligence Staff might agree that he had concluded his task, something inside told him that it was still incomplete; that something more, the unmasking of a deeper plot than either he or British headquarters at first suspected, remained to be done. Just what that was he did not know, but he had a vague suspicion, and at the moment he felt he was standing on the threshold of discoveries that might alter the whole course of the war in that part of the world. Moreover, it was unlikely that another British agent would ever again be in such a sound position to bring about the exposure; so it was up to him to hang on whatever the cost to himself.

* An attendant serving an officer. A position discontinued in today's Royal Air Force.

That von Stalhein was the super-spy, El Shereef, he no longer doubted, for it was hardly possible that there could be two German spies masquerading as Arabs behind the British lines, and that von Stalhein did adopt Arab disguise was certain; the incident at the oasis was sufficient proof of that. If further proof were needed there was the business of the feigned limp, which he felt was all part of a clever pose to throw possible investigators off the scent. The limp was so p.r.o.nounced, and he played the part of a lame man to such perfection, that the very act of abandoning it would have been a disguise in itself. No one could even think of von Stalhein without the infirmity. For what purpose other than espionage, or disguise, should he pretend to be incapacitated when he was not?

He knew now that von Stalhein was as active as any normal man. The way he had behaved when attacked by the Arab in his room revealed that, for he had dropped his sticks and dashed to the window with a speed that would have done credit to a professional runner. If he were not El Shereef, why the pose? As Erich von Stalhein he made his headquarters at Zabala; at night he changed, and under the pseudonym of El Shereef, worked behind the British lines, coming and going by means of a special detailed aeroplane. And the more Biggles thought about it the more he was convinced that he was right.

'The pilot flies him over, lands him well behind the lines-at the oasis for instance-and then comes home. Later, at a pre-arranged time and place, he goes over and picks him up,' he mused. 'That's what Mayer was doing the day he picked me up. Mayer landed for von Stalhein, but when he found me there instead he knew he had to bring me back. If only I could catch von Stalhein in the act of landing, there would be an end to it, but I'll bet he never again uses the place where I was picked up; he'd be too cunning for that; he doesn't trust me a yard, in spite of the fact that he has no foundation for his suspicions. He must have an instinct for danger like a cat. The only other way to nab him would be to find out the Arab name he adopts when he is over there, hanging about our troops picking up information. The thing I can't get over is that shadow on the tent, and but for the fact that he must have been somewhere around in order to learn that I was a prisoner, and then effect my rescue, I should feel inclined to think that I'd been mistaken.

It's rather funny he has never mentioned a thing to me, taken credit for getting me out of the mess. No, perhaps it isn't funny. Oh, dash it, I don't know . . . unless . .

He stared thoughtfully at the desert for some time, drumming on the window-sill with his fingers. 'Well, I'd better go and see what the Count wants, I suppose,' he concluded, as he finished his toilet and went down to the Mess to breakfast, after which he walked along to the fort. He found von Stalhein in the headquarters office, but the Count had not yet arrived.

'Good morning, Brunow,' greeted the German affably. 'Quite a good photo-look.' He pa.s.sed the last photograph Biggles had taken of Mayer's burning Halberstadt.

'Good morning, von Stalhein,' replied Biggles, taking it and looking at it closely, aware that that the German's eyes were on him. He finished his scrutiny and pa.s.sed it back, wondering if von Stalhein had overlooked something in the photograph which he had spotted instantly. The photograph had been taken from a very low alt.i.tude and from an oblique angle, which showed not only the charred, smoking wreck but the desert beyond.

Across the soft sand where he had landed ran a line of wheel tracks; they began some distance from the crash and ran off the top right-hand corner of the photograph. He looked up to see von Stalhein looking at him; his eyes were smiling mockingly, but there was no smile about his thin lips.
