Callously indifferent to the inspector's sufferings, Thorndyke continued calmly to examine the bar. At length, resting his lantern on the wall, he produced his pocket-lens, with which he resumed his investigation, a proceeding that so exasperated the inspector that that afflicted official limped off in dudgeon, followed by the station-master, and we heard him, presently, rapping at the front door of the house.
"Give me a slide, Jervis, with a drop of Farrant on it," said Thorndyke. "There are some fibres sticking to this bar."
I prepared the slide, and, having handed it to him together with a cover-glass, a pair of forceps and a needle, set up the microscope on the wall.
"I'm sorry for the inspector," Thorndyke remarked, with his eye applied to the little instrument, "but that was a lucky kick for us. Just take a look at the specimen."
I did so, and, having moved the slide about until I had seen the whole of the object, I gave my opinion. "Red wool fibres, blue cotton fibres and some yellow vegetable fibres that look like jute."
"Yes," said Thorndyke; "the same combination of fibres as that which we found on the dead man's teeth and probably from the same source.
