布鲁斯—帕廷顿计划（5）

 “Very good. The case is definite enough. The man, dead or alive, either fell or was precipitated from a train. So much is clear to me. Continue.”

“The trains which traverse the lines of rail beside which the body was found are those which run from west to east, some being purely Metropolitan, and some from Willesden and outlying junctions. It can be stated for certain that this young man, when he met his death, was travelling in this direction at some late hour of the night, but at what point he entered the train it is impossible to state.”

“His ticket, of course, would show that.”

“There was no ticket in his pockets.”

“No ticket! Dear me, Watson, this is really very singular. According to my experience it is not possible to reach the platform of a Metropolitan train without exhibiting one's ticket. Presumably, then, the young man had one. Was it taken from him in order to conceal the station from which he came? It is possible. Or did he drop it in the carriage? That is also possible. But the point is of curious interest. I understand that there was no sign of robbery?”

“Apparently not. There is a list here of his possessions. His purse contained two pounds fifteen. He had also a check-book on the Woolwich branch of the Capital and Counties Bank. Through this his identity was established. There were also two dress-circle tickets for the Woolwich Theatre, dated for that very evening. Also a small packet of technical papers.”

Holmes gave an exclamation of satisfaction.

“There we have it at last, Watson! British government—Woolwich. Arsenal—technical papers—Brother Mycroft, the chain is complete. But here he comes, if I am not mistaken, to speak for himself.”
