"That seems quite satisfactory," he said coldly. "Now ask the _Blucher_ her exact course?" Robins sat for a moment motionless. He felt Crawshay's presence towering over him, felt again the spell of his softly-spoken command. "Don't waste any time, please. Do as I tell you." Robins obeyed. In less than a quarter of an hour he handed over another slip of paper. Crawshay thrust it into his pocket. "That concludes our business," he said. "Now let me see if I remember enough of this apparatus to put it out of action." He bent over the instrument, removed some plugs, turned some screws, and finally placed in his pocket a small concealed part of the mechanism. Then he turned towards Robins. "You can leave here now," he directed. "I shall lock the place up." Robins had in some measure recovered himself. He was a quiet, hollow-eyed young person, with thick black hair and a thin frame, about which the uniform of the ship hung loosely. "You are the man who boarded the steamer from a seaplane, aren't you, and pretended afterwards to be such a ninny?" "I am," Crawshay acknowledged. "How did you get on to this?" Crawshay raised his eyebrows. "Sorry," he replied, "that is a matter concerning which I fear that you will have to restrain your curiosity." "How did you get in here?" "By means of a duplicate key which I obtained from the purser. I hid in your bunk there and drew the curtains. Quite a comfortable mattress, yours. You'll have to change your sleeping quarters, though." "What is going to happen to me?" the young man enquired. "Probably nothing extreme. You were philosophical enough to accept the situation. If," Crawshay went on more slowly, "you had falsified a single word of those messages, your end would have been somewhat abrupt and your destination according to your past life. As it is, you can go where you choose now and report to the captain later on in the morning, after I have had a talk with him." "My kit is all in here." Crawshay laid his hand upon the operator's shoulder in peremptory fashion. "Then you will have to do without it for the present," he replied coolly. "Outside." The young man turned on his heel and disappeared without a word. Crawshay glanced once more at the dismantled instrument, then followed Robins on to the deck, carefully locking the door behind him. A grey, stormy morning was just breaking, with piles of angry clouds creeping up, and showers of spray breaking over the ship on the weather side. He chose a sheltered spot and stood for a few moments breathing in the strong salt air. Notwithstanding his success, he was unaccountably depressed. As far as he could see across the grey waste of waters, there was no sign of any passing ship, but the eastern horizon was blurred by a low-hanging bank of sinister-looking clouds. Suddenly a voice rang out, hailing him. It was the captain descending from the bridge. "Come and have a cup of coffee with me in my room, Mr. Crawshay," he invited.
