“I’m afraid,” said Holmes, smiling, “that all the Queen’s horses and all the Queen’s men cannot avail in this matter.” He had spread out his big map of London and leaned eagerly over it. “Well, well,” said he presently with an exclamation of satisfaction, “things are turning a little in our direction at last. Why, Watson, I do honestly believe that we are going to pull it off, after all.” He slapped me on the shoulder with a sudden burst of hilarity. “I am going out now. It is only a reconnaissance. I will do nothing serious without my trusted comrade and biographer at my elbow. Do you stay here, and the odds are that you will see me again in an hour or two. If time hangs heavy get foolscap and a pen, and begin your narrative of how we saved the State.” I felt some reflection of his elation in my own mind, for I knew well that he would not depart so far from his usual austerity of demeanour unless there was good cause for exultation. All the long November evening I waited, filled with impatience for his return. At last, shortly after nine o’clock, there arrived a messenger with a note: Am dining at Goldini’s Restaurant, Gloucester Road, Kensington. Please come at once and join me there. Bring with you a jemmy, a dark lantern, a chisel, and a revolver.—S.H. 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 curaçao. 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.”
