Upon the dark cloth top of the table between them lay two large diamonds, declared by Pylotte to have been artificially made, the two with which he claimed to have been swindled.

Yet to the eyes of a layman they had all the qualities of natural gems, gleaming and glistening with magnificent fire in the cheerful sunlight of Nick's library.

Pylotte had invented a very clever and consistent story about himself and his mission in New York, as well as about the meeting and being victimized by the counterfeit diamond shover, and Nick as yet saw no occasion for seriously distrusting him, or connecting him with the Kilgore gang.

He rather suspected, in fact, that Pylotte had shadowed the swindler, whom Nick felt sure was Kilgore, with a view to learning just how the diamonds had been manufactured, and possibly with a design to turn the discovery to his own advantage.

This was, indeed, the most natural deduction for Nick to arrive at, after considering all the circumstances.

"I am absolutely sure of it, Mr. Carter," declared Pylotte.

"Have you any idea how such counterfeits can be made?"

"Oh, yes."

"By what process and means, Mr. Pylotte?"
