"They're safe," said Tom. "We left them on the island. They're quite safe. Oh, Daddy—isn't this too good to be true I Daddy, this is Andy. He's been such a brick. Weld never have escaped if it hadn't been for him."
"What do you mean—escaped!" said Tom's father, in surprise. "Escaped from what?"
"We've got a big secret to tell you," said Tom. "We've found out something queer. You tell him. Andy."
"Well, sir," said Andy, "we got thrown off up the coast of some desolate islands where nobody lives now. The enemy are using them for their submarines and seaplanes. There are caves stored with food—and there" must be stores of fuel somewhere, too."
"What!" shouted Tom's father. He called his men near and they all listened to Andy's tale. The boy told it well.
"And we were just escaping on the raft we had made when we saw you," finished Andy. "We slipped over the side of the raft to hide—but you must have seen us."
"We didn't," said Tom's father. "But we were puzzled about the empty raft and came down to examine it. Little did we think you and Andy were there! This seaplane and two others have been scouring the seas about here looking for the sailing-ship you went off in. We were afraid you might be drifting about in it, half-starving. Your poor mother has been dreadfully upset."
"Oh dear, I was afraid she would be," said Tom. "But, never mind, we're all safe, Daddy—at least, I hope the girls are safe!"
"They will be, very soon," said the boy's father in a grim voice. "We shall rescue them—and clean up those submarines and seaplanes in no time! How clever of the enemy to have a base just under our noses—but it won't last long now! You've done a marvellous thing, Tom and Andy!"
"I hope my father won't be very angry with me for losing his boat," said Andy. "Though we might perhaps be able to get it back from the enemy now."
"Your father won't be angry with you for anything once he sees you are safe, and hears the tale you have just told me!" said Tom's father. "Settle down now—we're going up."
"Back to the island to rescue the girls?" asked Tom eagerly. His father shook his head.
"No," he said. "They must wait, I'm afraid, till I get this news through. I'll wireless home that we've got you safe, and have got great news—but that's all. This is too important to be told to anyone but the chief himself."
With a great noise of engines, the seaplane skimmed over the water, and then rose gracefully in the air. She shot away southwards, and the boys looked out over the sea, which was now far below.
"Well, what luck to be rescued like this!" said Andy. "And oh, Tom—what a shock the enemy are going to get!"
Chapter 24
What Happened to the Girls
The two girls felt very lost and lonely when the boys went off on the raft. They climbed the cliff quickly so that they might watch the boys till they were out of sight.
They waved until the raft was a tiny speck on the sea. Then they lost sight of it. It was gone.
"I do hope Tom and Andy reach home all right," said Jill, as they made their way down the cliff to the shore again. "It would be awful if they got lost on the sea."
"Don't say things like that!" said Mary. "Let's think of something cheerful. Let's have something to eat."
But neither of them really wanted anything. They kept thinking of the two brave boys on their little raft.
"I do hope nobody combs to the island to-day," said Mary. "I don't feel as if I shall be able to act very well."
Nobody did come that day. The girls were left quite alone. They bathed in the sea and dried themselves in the sun. Then they bathed all over again. There really wasn't much else to do!
They missed the two boys very much, and when night came they even felt a little frightened.
"Cheer up!" said Jill, seeing Mary's long face. "We shall be all right cuddled up in the tent together! The enemy don't know the boys are gone—that's the main thing. I should think the boys are pretty safe by now—there has been a good wind blowing all day and they must have gone a long way already."
The girls lighted their little stove and put it just at the tent-opening when night came. They liked to see the small light it gave. They boiled a kettle of water on it and sat inside the tent, drinking hot cocoa, whilst the stars came out in the sky.
As they were about to curl up and go to sleep they heard the sound of a seaplane droning overhead. It came over the island twice, and then went away.
And then, about an hour later, the girls heard the noise of the motor-boat! It grounded on the sand of the cove and the girls heard men's voices.
"Good gracious!" said Jill, sitting up in alarm. "What are they coming here at this time of night for? They will soon see the boys aren't here! Quick, Mary, get up. We'll slip out of the tent and go into the bracken. Maybe we can pretend we've been roaming over the island, and they'll think the boys are somewhere about too."
The girls left the tent and ran into the heather and bracken in the middle of the small island. The men left their boat on the beach and two of them came up to the tent.
They lifted the flap of the tent and flashed a torch inside. There was no one there, of course! One of the men called out loudly.
"Now, you children! Where are you?"
"Here!" answered Jill. She nudged Mary. "You shout too," she whispered. "Then I'll shout again, and they'll think we are all here."
"We're here!" yelled Mary valiantly, though her heart was beating hard.
"In the bracken!" shouted Jill.
"Come along down here," commanded the man. He was the one who could speak English.
"We shall have to go," said Jill. "Now don't you give the boys away, Mary. Pretend they are about somewhere."
The girls made their way to the men, who flashed a light on them.
"Where are the boys?" demanded the man.
"Haven't you seen them?" asked Jill. "They must be about somewhere. Maybe they are in the tent. Have you looked?"
"Yes," said the man. "Now look here—what do you mean by lighting this stove out here? Are you trying to signal to anyone?"
"Good gracious! Of course not!" said Jill. "We only made some hot cocoa, that's all. Look—there are our dirty cups."
She wished she had not said this when the man looked for the cups—for he saw at once that there were only two! He looked at Jill suspiciously.
"Why did the boys not have the cocoa?" he asked.
"They weren't here when we made it," said Jill. "Why don't you go and look for them?"
The man turned out the stove, and the light flickered and went out. "Now don't you dare to show a light at nights," he said. "If I think you are signalling to anyone you will be very sorry!"
"Who could we signal to?" asked Jill. "We don't even know where we are!"
The man took no notice of her. He stood and shouted into the night. "Boys! Come here at once!"
There was no answer, of course—there couldn't be, for the boys were miles away on the sea.
"To-morrow I will come to tell those boys that when I call, they must answer," said the man in an angry voice, "I am going now—but to-morrow I come again. You will tell the boys they must be here, by the tent."
Jill and Mary said nothing. They could not tell the boys—and they wondered what would happen when the men found that they were not on the island.
The men went off in their boat again. "What a pity we lighted that stove!" said Jill. "I suppose that seaplane saw it and reported it—and they thought we were signalling to someone. How clever they must think us! I only wish we could signal to someone!"
