alight while it was moving at that rate through the darkness would be equivalent to committing suicide. At the best he could not hope to avoid serious injury. He must wait--till it slowed. The whistle on the engine sounded; the train began to slow. Instantly he was leaning forward, his fingers on the handle, which was inside the door. The train slowed still more; it entered a tunnel, slowing all the while; in the heart of the tunnel it stopped--dead. The gods were on his side. Yet not for an instant did he lose his presence of mind. The signal was against them--that was why they had stopped. Was it on the left or the right? On the signal side the guard would possibly have his head out of the carriage with an eye for it; possibly some of the passengers might be observing it also. It would be fatal to get out on that side; his door would be seen opening; he might be seen to alight; he would be jumping out of the frying-pan into the fire; all sorts of consequences might accrue. He looked out of his own window; there was no signal in front or behind. Then it was on the other side, on the left, against the wall of the tunnel. He looked on to the six-foot way. He could see the whole length of the train; not a sign of a head at any of the windows. He had already turned the handle, opening the door just wide enough he stepped on to the footboard, closed the door, and dropped on to the permanent way. He had left his uncle to continue his journey alone. Lest his upstanding figure might be visible to someone, he crouched as close as he could to the ground. The train began to move very slowly. The door of the compartment next to that which he had just left was opened, a figure came on to the footboard, closed the door, sprang on to the ballast while the train was already in motion. For a moment Rodney was the victim of a gruesome delusion; to him it was as if the door of his own compartment had been opened; as if Graham Patterson had alighted at his side. He pressed the tips of his fingers into his palms to keep himself from exclaiming. CHAPTER XI THE STRANGER
