As he spoke he went along the corridor, rapidly glancing into every compartment. In one, three men were asleep, obviously unaware that anyone was surveying them from outside. The door of the compartment was ajar, and the stranger noiselessly stepped within. The fourth corner was unoccupied, and here the man took his seat, laying his bundle down beside him, and feigning sleep. He waited, motionless, for a good quarter of an hour, until he was quite satisfied that his companions were really sleeping soundly, then he slid his hand into the bundle by his side, seemed to be doing something inside it, then withdrew his hand noiselessly, stepped out of the compartment, and carefully closed the door.
In the corridor he drew a sigh of relieved satisfaction, and took a cigar from his pocket.
"Everything is going splendidly," he said to himself. "I was cursing this awful storm just now, but it is wonderfully useful to me. On such a night as this no one would dream of opening the windows." He strolled up and down, holding on to the hand-rail with one hand to maintain himself against the rocking of the train, and every now and then taking out his watch with the other to see the time. "I haven't any too much time," he muttered. "I shall have to be quick, or my friend will miss his train!" He smiled, as if amused at the idea, and then, holding his cigar away from him so as not to inhale the smoke, he drew several deep breaths. "There is a faint smell," he said, "but you would have to be told of it to detect it. The devil of it is that it so often causes nightmare; that would be awful!" He suspended his patrol and listened again. There was no sound to be heard from within the compartments except the snoring of a few travellers and the monotonous, rhythmical noise of the wheels passing over the joints of the rails. "Come: I've waited twenty minutes; it would be risky to wait longer; let's get to work!"
He stepped briskly back into the compartment, and furtively glancing into the corridor to make sure that no one was there, he went across to the opposite window and opened it wide. He put his head out into the air for a minute or two, and then turned to examine his travelling companions. All three were still sound asleep.
The man gave vent to a dry chuckle. He drew his bundle towards him, felt until he found something within it, and flung it back on to the seat. Then he walked up to the man opposite him, slipped his hand inside his coat and abstracted a pocket-book and began to examine the papers it contained. "Ah!" he exclaimed suddenly; "that was what I was afraid of!" and taking one of the papers he put it inside his own pocket-book, chose one from his own and put it into the other man's pocket-book, and then, having effected this exchange, replaced the man's property and chuckled again. "You do sleep!"
And indeed, although the pick-pocket took no particular precaution, the man continued to sleep soundly, as did the other two men in the compartment.
The thief looked once more at his watch.
"Time!"
He leaned out of the open window and slipped back the safety catch. Then he opened the door quite wide, took the sleeping traveller by the shoulders and picked him up from the seat, and with all his strength sent him rolling out on to the line!
The next moment he seized from the rack the light articles that evidently belonged to his victim, and threw them out after him.
