"I regret that it was necessary to smash your window," said Captain Bernstein, as the queer group gathered round the lamp in Peter's living room. "But we might have died out there on a night like this, before you could have heard us shouting. We shall not harm you, although there are four of us. We are in danger ourselves. My friends and I are sick of this work; and, if we are sure of good treatment, we are prepared to help the British with all the information in our possession."
"How did you escape from the submarine?" said Peter.
"We were alone on deck," replied Bernstein, "and we took our chance of swimming for the Hatchets'."
Peter surveyed the four drenched figures thoughtfully. One of them was not realistic enough to satisfy him. There were several obviously dry patches about the shoulders.
"There's a pool on the reef," said Peter at last to this man. "Did you find it too cold?"
A change came over Bernstein's face at once.
"There's no time to be wasted," he said. "If you want to help your country, go to your telephone and give this message to the naval base, exactly as I tell it to you. You must say you have just sighted three submarines, two hundred yards due north of the Hatchets' light. You must say that you have sighted them yourself, because they would not take our word for it; and you must not say anything about our being here at present. If you depart from these instructions, you will be shot instantly. Now, then, go to your telephone and speak."
Peter gathered up his beloved leather-bound book from the table, and held it under his arm. It was his most precious possession, and the protective act was quite unconscious. Then, for the second time that night, he went into his bedroom, followed by the four Germans. He was white and shaking. He could not understand what these men were after, and the message they proposed seemed to be useful to his own side. After all, the only kind of message that he could send would be something very like it. He might as well deliver it, since these crazy autocrats had decided that it must be given thus, and not otherwise.
He laid the precious book down on the bed, turned to the telephone, and lifted the receiver to his ear. As he did so, the cold muzzle of a revolver pressed against his right temple. The first buzzings of the telephone resolved themselves into a voice from the coast of England, asking what he wanted. Then, it seemed as if a new light were thrown upon the character of the words he was about to speak. He knew instinctively that, if he spoke them, he would be working for the enemy.
In the same instant, he saw exactly what he must do.
