布鲁斯—帕廷顿计划（26）

 It was a nice equipment for a respectable citizen to carry through the dim, fog-draped streets. I stowed them all discreetly away in my overcoat and drove straight to the address given. There sat my friend at a little round table near the door of the garish Italian restaurant.

“Have you had something to eat? Then join me in a coffee and curacao. Try one of the proprietor's cigars. They are less poisonous than one would expect. Have you the tools?”

“They are here, in my overcoat.”

“Excellent. Let me give you a short sketch of what I have done, with some indication of what we are about to do. Now it must be evident to you, Watson, that this young man's body was placed on the roof of the train. That was clear from the instant that I determined the fact that it was from the roof, and not from a carriage, that he had fallen.”

“Could it not have been dropped from a bridge?”

“I should say it was impossible. If you examine the roofs you will find that they are slightly rounded, and there is no railing round them. Therefore, we can say for certain that young Cadogan West was placed on it.”

“How could he be placed there?”

“That was the question which we had to answer. There is only one possible way. You are aware that the Underground runs clear of tunnels at some points in the West End. I had a vague memory that as I have travelled by it I have occasionally seen windows just above my head. Now, suppose that a train halted under such a window, would there be any difficulty in laying a body upon the roof?”

“It seems most improbable.”
