Facing the German foe Part 18

For the officer who had arrested him he felt a good deal of contempt. While it was true that orders had to be obeyed, there was no reason, Harry felt, why the lieutenant should not have shown some discretion. An officer of the regular army would have done so, he felt. But this man looked unintelligent and stupid. Harry felt that he might safely rely on his appearance. And he was right. The officer found himself in a quandary at once. His men were mounted on cycles; Harry was on foot. And Harry saw that he didn't quite know what to do.

Finally he cut the Gordian knot, as it seemed to him, by impounding a bicycle from a pa.s.sing wheel-man, who protested vigorously but in vain. All he got for his cycle was a sc.r.a.p of paper, stating that it had been requisitioned for army use. And Harry was instructed to mount this machine and ride along between two of the territorial soldiers. He had been hoping for something like that, but had hardly dared to expect it. He had fully made up his mind now to take all the risks he would run by trying to escape. He could not get clear away, that much he knew. But now he, too, like Graves, needed a little time. He did not mind being recaptured in a short time if, in the meanwhile, he could be free to do what he wanted.

As to just how he would try to get away, he did not try to plan. He felt that somewhere along the route some chance would present itself, and that it would be better to trust to that than to make some plan. He was ordered to the front of the squad--so that a better eye could be kept upon him, as the lieutenant put it. Harry had irritated him by his attempts to cause a change in the disposition of Graves and himself, and the officer gave the impression now that he regarded Harry as a desperate criminal, already tried and convicted.

Harry counted upon the traffic, sure to increase as it grew later, to give him his chance. Something accidental, he knew, there must be, or he would not be able to get away. And it was not long before his chance came. As they crossed a wide street there was a sudden outburst of shouting. A runaway horse, dragging a delivery cart, came rushing down on the squad, and in a moment it was broken up and confused. Harry seized the chance. His bicycle, by a lucky chance, was a high geared machine and before anyone knew he had gone he had turned a corner. In a moment he threw himself off the machine, dragged it into a shop, ran out, and in a moment dashed into another shop, crowded with customers. And there for a moment, he stayed.

There was a hue and cry outside. He saw uniformed men, on bicycles, dashing by. He even rushed to the door with the crowd in the shop to see what was amiss! And, when the chase had pa.s.sed, he walked out, very calmly, though his heart was in his mouth, and quite unmolested got aboard a pa.s.sing tram car.

He was counting on the stupidity and lack of imagination of the lieutenant, and his course was hardly as bold as it seems. As a matter of fact it was his one chance to escape. He knew what the officer would think--that, being in flight, he would try to get away as quickly as possible from the scene of his escape. And so, by staying there, he was in the one place where no one would think of looking for him!

On the tram car he was fairly safe. It happened, fortunately, that he had plenty of money with him. And his first move, when he felt it was safe, was to get off the tram and look for a cab. He found a taxicab in a short time, one of those that had escaped requisition by the government, and in this he drove to an outfitting shop, where he bought new clothes. He reasoned that he would be looked for all over, and that if, instead of appearing as a Boy Scout in character dress of the organization, he was in the ordinary clothes, he would have a better chance. He managed the change easily, and then felt that it was safe for him to try to get into communication with d.i.c.k.

In this attempt luck was with him again. He called for the number of the vicarage at Bray, only to find that the call was interrupted again at the nearest telephone center. But this time he was asked to wait, and in a moment he heard Jack Young's voice in his ear.

"We came over to explain about the wire's being cut," said Jack. "d.i.c.k's all right. He's here with me. Where are you? We've got to see you just as soon as we can."

"In London, but I'm coming down. I'm going to try to get a motor car, too.

I'm in a lot of trouble, Jack--it's Graves."

"Come on down. We'll walk out along the road toward London and meet you.

We've got a lot to tell you, but I'm afraid to talk about it over the telephone."

"All right! I'll keep my eyes open for you."

Getting a motor car was not easy. A great many had been taken by the government. But Harry remembered that one was owned by a business friend of his father's, an American, and this, with some difficulty, he managed to borrow. He was known as a careful driver. He had learned to drive his father's car at home, and Mr. Armstrong knew it. And so, when Harry explained that it was a matter of the greatest urgency, he got it--since he had established a reputation for honor that made Mr. Armstrong understand that when Harry said a thing was urgent, urgent it must be.

Getting out of London was easy. If a search was being made for him--and he had no doubt that that was true--he found no evidence of it. His change of clothes was probably what saved him, for it altered his appearance greatly.

So he came near to Bray, and finally met his two friends.

CHAPTER XVI

THE CIPHER

"What happened to you?" asked Jack and d.i.c.k in chorus.

Swiftly Harry explained. He told of his arrest as a spy and of his escape.

And when he mentioned the part that Ernest Graves had played in the affair, Jack and d.i.c.k looked at one another.

"We were afraid of something like that," said Jack. "Harry, we've found out a lot of things, and we don't know what they mean! We're sure something dreadful is going to happen to-night. And we're sure, too, that Bray Park is going to be the centre of the trouble."

"Tell me what you know," said Harry, crisply. "Then we'll put two and two together. I say, Jack, we don't want to be seen, you know. Isn't there some side road that doesn't lead anywhere, where I can run in with the car while we talk?"

"Yes. There's a place about a quarter of a mile further on that will do splendidly," he replied.

"All right. Lead the way! Tell me when we come to it. I've just thought of something else I ought never to have forgotten. At least, I thought of it when I took the things out of my pockets while I was changing my clothes."

They soon came to the turning Jack had thought of, and a run of a few hundred yards took them entirely out of sight of the main road, and to a place where they were able to feel fairly sure of not being molested.

Then they exchanged stories. Harry told his first. Then he heard of d.i.c.k's escape, and of his meeting with Jack. He nodded at the story they had heard from Gaffer Hodge.

"That accounts for how Graves knew," he said, with much satisfaction. "What happened then?"

When he heard of how they had thought too late of calling Colonel Throckmorton by telephone he sighed.

"If you'd only got that message through before Graves got in his work!" he said. "He'd have had to believe you then, of course. How unlucky!"

"I know," said Jack. "We were frightfully sorry. And then we went out to find where the wire was cut, and they got d.i.c.k. But I got away, and I managed to stay fairly close to them. I followed them when they left d.i.c.k in a little stone house, as a prisoner, and I heard this--I heard them talking about getting a big supply of petrol. Now what on earth do they want petrol for? They said there would still be plenty left for the automobiles--and then that they wouldn't need the cars any more, anyhow!

What on earth do you make of that, Harry?"

"Tell me the rest, then I'll tell you what I think," said Harry. "How did you get d.i.c.k out? And did you hear them saying anything that sounded as if it might be useful, d.i.c.k?"

"That was fine work!" he said, when he had heard a description of d.i.c.k's rescue. "Jack, you seem to be around every time one of us gets into trouble and needs help!"

Then d.i.c.k told of the things he had overheard--the mysterious references to Von Wedel and to things that were to be done to the barracks at Ealing and Houndsditch. Harry got out a pencil and paper then, and made a careful note of every name that d.i.c.k mentioned. Then he took a paper from his pocket.

"Remember this, d.i.c.k?" he asked. "It's the thing I spoke of that I forgot until I came across it in my pocket this morning."

"What is it, Harry?"

"Don't you remember that we watched them heliographing some messages, and put down the Morse signs? Here they are. Now the thing to do is to see if we can't work out the meaning of the code. If it's a code that uses words for phrases we're probably stuck, but I think it's more likely to depend on inversions."

"What do you mean, Harry?" asked Jack. "I'm sorry I don't know anything about codes and ciphers."

"Why, there are two main sorts of codes, Jack, and, of course, thousands of variations of each of those princ.i.p.al kinds. In one kind the idea is to save words--in telegraphing or cabling. So the things that are likely to be said are represented by one word. For instance _Coal_, in a mining code, might mean 'Struck vein at two hundred feet level.' In the other sort of code, the letters are changed. That is done in all sorts of ways, and there are various tricks. The way to get at nearly all of them is to find out which letter or number or symbol is used most often, and to remember that in an ordinary letter E will appear almost twice as often as any other letter--in English, that is."

"But won't this be in German?"

"Yes. That's just why I wanted those names d.i.c.k heard. They are likely to appear in any message that was sent. So, if we can find words that correspond in length to those, we may be able to work it out. Here goes, anyhow!"

For a long time Harry puzzled over the message. He transcribed the Morse symbols first into English letters and found they made a hopeless and confused jumble, as he had expected. The key of the letter E was useless, as he had also expected. But finally, by making himself think in German, he began to see a light ahead. And after an hour's hard work he gave a cry of exultation.

"I believe I've got it!" he cried. "Listen and see if this doesn't sound reasonable!"

"Go ahead!" said Jack and d.i.c.k, eagerly.

"Here it is," said Harry. "'Petrol just arranged. Supply on way. Reach Bray Friday. Von Wedel may come. Red light markers arranged. Ealing Houndsditch Buckingham Admiralty War Office. Closing.'"

They stared at him, mystified.

"I suppose it does make sense," said d.i.c.k. "But what on earth does it mean, Harry?"

"Oh, can't you see?" cried Harry. "Von Wedel is a commander of some sort--that's plain, isn't it? And he's to carry out a raid, destroying or attacking the places that are mentioned! How can he do that? He can't be a naval commander. He can't be going to lead troops, because we know they can't land. Then how can he get here? And why should he need petrol?"

They stared at him blankly. Then, suddenly, d.i.c.k understood.
