Mr. Rufus Venner, it may be here stated, was a man of about forty years of age, and was a very well-known man about town. Darkly handsome, with an erect and imposing figure, an habitué of the best clubs, a man still unmarried, yet of whom hints were frequently dropped that he was very popular with the fair sex, whom he was known to lavishly entertain at times—this was the senior member of the firm of Venner & Co., and the man who, quickly arose to greet Nick Carter and Chick when the two detectives entered.

"Your clerk has already given me the main facts of the case, Mr. Venner, so we will dispense with any rehearsal of them, and get right down to business," Nick crisply observed, immediately after their greeting. "There are a few questions I wish to ask you, and concise replies may expedite matters."

"I will respond as briefly as possible, Mr. Carter," Venner quickly rejoined, as they took chairs around the office table. "I do not fancy being robbed in this scurvy fashion, sir, and you may go to any reasonable expense to discover and arrest the thieves. Now, Detective Carter, your questions?"

"To begin with," asked Nick, with a steadfast scrutiny of Venner's darkly attractive face, "what is the value of the stolen diamonds?"

"About four thousand dollars."

"Ten in number, I was told."

"Precisely."

"Are they of uniform value?"

"Nearly so. They are splendid gems, and perfectly matched, and are worth about four hundred dollars each. I wanted them for a special purpose, which—"

"Which I will presently arrive at," Nick courteously interposed. "I understand, Mr. Venner, that you called yesterday at the store of Thomas Hafferman and made some inquiries about these stones?"
