Near what had been the rear end he stopped, and drew from his pocket a piece of paper; then, with a moistened finger-tip he picked up from the footboard some evidently minute object, which he carefully transferred to the paper, folding the latter and placing it in his pocket-book.
He next mounted the footboard, and, having peered in through the window of the sealed compartment, produced from his pocket a small insufflator or powder-blower, with which he blew a stream of impalpable smoke-like powder on to the edges of the middle window, bestowing the closest attention on the irregular dusty patches in which it settled, and even measuring one on the jamb of the window with a pocket-rule. At length he stepped down, and, having carefully looked over the near-side footboard, announced that he had finished for the present.
As we were returning down the line, we passed a working man, who seemed to be viewing the chairs and sleepers with more than casual interest.
"That, I suppose, is one of the plate-layers?" Thorndyke suggested to the station-master.
"Yes, the foreman of the gang," was the reply.
"I'll just step back and have a word with him, if you will walk on slowly." And my colleague turned back briskly and overtook the man, with whom he remained in conversation for some minutes.
"I think I see the police inspector on the platform," remarked Thorndyke, as we approached the station.
"Yes, there he is," said our guide. "Come down to see what you are after, sir, I expect." Which was doubtless the case, although the officer professed to be there by the merest chance.
"You would like to see the weapon, sir, I suppose?" he remarked, when he had introduced himself.
"The umbrella-spike," Thorndyke corrected. "Yes, if I may. We are going to the mortuary now."
