An hour later Holmes, Lestrade and I stood upon the Underground railroad at the point where it emerges from the tunnel immediately before Aldgate Station. A courteous red-faced old gentleman represented the railway company.
"This is where the young man's body lay," said he, indicating a spot about three feet from the metals. "It could not have fallen from above, for these, as you see, are all blank walls. Therefore, it could only have come from a train, and that train, so far as we can trace it, must have passed about midnight on Monday."
"There are no such signs, and no ticket has been found."
"No record of a door being found open?"
"None."
"We have had some fresh evidence this morning," said Lestrade. "A passenger who passed Aldgate in an ordinary Metropolitan train about 11:40 on Monday night declares that he heard a heavy thud, as of a body striking the line, just before the train reached the station. There was dense fog, however, and nothing could be seen. He made no report of it at the time. Why, whatever is the matter with Mr. Holmes?"
"Points," he muttered; "the points."
"What of it? What do you mean?"
"I suppose are no great number of points on a system such as this?"
"No; they are very few."
"And a curve, too. Points, and a curve. By Jove! if it were only so."
"is it, Mr. Holmes? Have you a clue?"
"An idea--an indication, no more. But the case certainly grows in interest. Unique, perfectly unique, and yet why not? I do not see any indications of bleeding on the line."
"There were hardly any."
"But I understand that there was a considerable wound."
"The bone was crushed, but there was no great external injury."
"And yet one would have expected some bleeding. Would it be possible for me to inspect the train which contained the passenger who heard the thud of a fall in the fog?"
"I fear not, Mr. Holmes. The train has been broken up before now, and the carriages redistributed."
"I can assure you, Mr. Holmes," said Lestrade, "that every carriage has been carefully examined. I saw to it myself."
