"None of your business," exclaimed the merchant, passionately.

"I beg your pardon, but I was blamed by my employer for not taking down the name of the purchaser, and I told him in return that I would gather full particulars."

"You may tell him it is all right. He must have heard of me and of my firm, and that will satisfy him."

"But the name of this gentleman in Thirty-seventh Street——"

"It is not necessary to the purpose."

"Has there been a death in his family within ten days?" asked the clerk in quiet tones, but there was a significance in them which sent a thrill through the frame of his listener.

"What makes you ask that?" he stammered.

"I will tell you," said James Cromwell, boldly throwing off his reserve. "It is as well to be frank, and there is no use in mincing matters. I do not believe this story of the man in Thirty-seventh Street. I think you bought the article for your own use. Since the purchase there has been a death in your house."

"Your inference is ridiculous," said the merchant, nervously. "My intimate and dear friend, Mr. Raymond, was sick of an incurable disease, as the physician will testify, and it could have terminated in no other way."

"I am quite willing to believe you are right," said the clerk. "Still, under the circumstances, you will not object to an investigation. I feel it my duty to inform a coroner of the facts in the case, and if on examination no traces of the action of poison can be found in the deceased, of course you are entirely exonerated from suspicion!"
