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.
