with his forceps some minute object from between two of the upper front teeth and held it in the focus of the lens. Anticipating his next move, I took a labelled microscope-slide from the case and handed it to him together with a dissecting needle, and, as he transferred the object to the slide and spread it out with the needle, I set up the little microscope on the shelf.
"A drop of Farrant and a cover-glass, please, Jervis," said Thorndyke.
I handed him the bottle, and, when he had let a drop of the mounting fluid fall gently on the object and put on the cover-slip, he placed the slide on the stage of the microscope and examined it attentively.

"I was thinking, sir," he said apologetically, "that it's a bit off the track to be finding out what he had for dinner. He didn't die of unwholesome feeding."
Thorndyke looked up with a smile. "It doesn't do, inspector, to assume that anything is off the track in an inquiry of this kind. Every fact must have some significance, you know."
"I don't see any significance in the diet of a man who has had his head cut off," the inspector rejoined defiantly.
