The Boy Scout Aviators Part 7

"Will I!" said d.i.c.k. "What do you think you'll do, Harry?"

"We may get special orders, of course," said Harry. "But I think the first thing will be to find out just where the signals from that house are being received. They must be answered, you know, so we ought to find the next station. Then, from that, we can work on to the next."

"Where do you suppose those signals go to?"

"That's what we've got to find out, d.i.c.k! But I should think, in the long run, to someplace on the East coast. Perhaps they've got some way there of signalling to ships at sea. Anyhow, that's what's got to be discovered. Did you see Graves tonight?"

"No," said d.i.c.k, his lips tightening, "I didn't! But I heard about him, all right."

"How? What do you mean?"

"I heard that he'd been doing a lot of talking about you. He said it wasn't fair to have taken you and given you the honor of doing something when there were English boys who were just as capable of doing it as you."

"Oh!" said Harry, with a laugh. "Much I care what he says!"

"Much I care, either!" echoed d.i.c.k. "But, Harry, he has made some of the other chaps feel that way, too. They all like you, and they don't like him. But they do seem to think some of them should have been chosen."

"'Well, it's not my fault," said Harry, cheerfully. "I certainly wasn't going to refuse. And it isn't as if I'd asked Mr. Wharton to pick me out."

"No, and I fancy there aren't many of them who would have done as well as you did today, either!"

"Oh yes, they would! That wasn't anything. We'd better get to bed now. I think we ought to report just as early as we can in the morning. If we get away by seven o'clock, it won't be a bit too early."

"All right. I'll be ready. Good-night, Harry!"

"Good-night, d.i.c.k!"

Morning saw them up on time, and off to Ealing. There Colonel Throckmorton gave them their orders.

"I've requisitioned motorcycles for you," he said. "Make sure of the location of the house, so that you can mark it on an ordnance map for me. Then use your own judgment, but find the next house. I have had letters prepared for you that will introduce you to either the mayor or the military commander in any town you reach and you will get quarters for the night, if you need them. Where do you think your search will lead you, Fleming?"

He eyed Harry sharply as he asked the question. "Somewhere on the East coast, I think, sir," replied Harry.

"Well, that remains to be seen. Report by telegraph, using this code.

It's a simplified version of the official code, but it contains all you will need to use. That is all."

Finding the house, when they started on their motorcycles, did not prove as difficult a task as Harry had feared it might. They both remembered a number of places they had marked from the cab windows, and it was not long before they were sure they were drawing near.

"I remember that hill," said Harry. "By Jove--yes, there it is! On top of that hill, do you see? We won't go much nearer. I don't want them to see us, by any chance. All we need is to notice which way they're signalling."

They watched the house for some time before there was any sign of life.

And then it was only the flashes that they saw. Since the previous day some sort of cover had been provided for the man who did the signalling.

"What do you make of it, d.i.c.k?" asked Harry eagerly, after the flashing had continued for some moments.

"It looks to me as if they were flashing toward the north and a little toward the west," said d.i.c.k, puzzled.

"That's the way it seems to me, too," agreed Harry. "That isn't what we expected, either, is it?"

"Of course we can't be sure."

"No, put it certainly looks that way. Well, we can't make sure from here, but we've got to do it somehow. I tell you what. We'll circle around and get northwest of the house. Then we ought to be able to tell a good deal better. And if we get far enough around, I don't believe they'll see us, or pay any attention to us if they do."

So they mounted their machines again, and in a few moments were speeding toward a new and better spot from which to spy on the house. But this, when they reached it, only confirmed their first guess. The signals were much more plainly visible here, and it was obvious now, as it had not been before, that the screen they had noticed had been erected as much to concentrate the flashes and make them more easily visible to a receiving station as to conceal the operator. So they turned and figured a straight line as well as they could from the spot where the flashes were made. Harry had a map with him, and on this he marked, as well as he could, the location of the house. Then he drew a line from it to the northwest.

"The next station must be on this line somewhere," he said. "We'll stick to it. There's a road, you see, that we can follow that's almost straight. And as soon as we come to a high building we ought to be able to see both flashes--the ones that are being sent from that house and the answering signals. Do you see?"

"Yes, that'll be fine!" said d.i.c.k. "Come on!"

"Not so fast!" said a harsh voice behind them.

They spun around, and there, grinning a little, but looking highly determined and dangerous, was the same man they had seen the day before, and who had questioned them when the tire of their taxicab blew out! But now he was not in uniform, but in a plain suit of clothes.

"So you are spying on my house, are you?" he said. "And you lied to me yesterday! No troops were sent to Croydon at all!"

"Well, you hadn't any business to ask us!" said d.i.c.k, pluckily. "If you hadn't asked us any questions, we'd have told you no lies."

"I think perhaps you know too much," said the spy, nodding his head, "You had better come with me. We will look after you in this house that interests you so greatly."

He made a movement forward. His hand dropped on d.i.c.k's shoulder. But as it did so Harry's feet left the ground. He aimed for the spy's legs, just below the knee, and brought him to the ground with a beautiful diving tackle--the sort he had learned in his American football days. It was the one attack of all others that the spy did not antic.i.p.ate, if, indeed, he looked for any resistance at all. He wasn't a football player, so he didn't know how to let his body give and strike the ground limply. The result was that his head struck a piece of hard ground with abnormal violence, and he lay p.r.o.ne and very still.

"Oh, that was ripping, Harry!" cried d.i.c.k. "But do you think you've killed him?"

"Killed him? No!" said Harry, with a laugh.

"He's tougher than that, d.i.c.k!"

But he looked ruefully at the spy.

"I wish I knew what to do with him," he said. "He'll come to in a little while. But--"

"We can get away while he's still out," said d.i.c.k, quickly. "He can't follow us and we can get such a start with our motorcycles."

"Yes, but he'll know their game is up," said Harry. "Don't you see, d.i.c.k? He'll tell them they're suspected--and that's all they'll need in the way of warning. When men are doing anything as desperate as the sort of work they're up to in that house, they take no more chances than they have to. They'd be off at once, and start up somewhere else. We only stumbled on this by mere accident--they might be able to work for weeks if they were warned."

"Oh, I never thought of that! What are we to do, then?'

"I wish I knew whether anyone saw us from the house or if they didn't--!

Well, we'll have to risk that. d.i.c.k, do you see that house over there?

It's all boarded up--it must be empty."

"Yes, I see it." d.i.c.k caught Harry's idea at once this time, and began measuring with his eye the distance to the little house of which Harry had spoken. "It's all down hill--I think we could manage it all right."

"We'll try it, anyhow," said Harry. "But first we'd better tie up his hands and feet. He's too strong for the pair of us, I'm afraid, if he should come to."

Once that was done, they began to drag the spy toward the house. Half carrying, half pulling, they got him down the slope, and with a last great effort lifted him through a window, which, despoiled of gla.s.s, had been boarded up. They were as gentle as they could be, for the idea of hurting a helpless man, even though he was a spy, went against the grain. But--

"We can't be too particular," said Harry. "And he brought it on himself.
