scarab,—whether a real one or not I couldn’t tell,—and was set on a flat backing of gold. This back might easily retain the thumb print of the woman who had drawn that pin from her hat in Mr. Gately’s office. And who, Norah surmised, was the person who had fired the pistol that I had heard discharged. Placing the hatpin in the drawer with the checkbook, Mr. Talcott locked the drawer and slipped the key in his pocket. I wondered if he had seen some entry in the book that made him wish to hide Mr. Gately’s private affairs from curious eyes. “There is indeed a possibility of something wrong,” he went on, “at first I couldn’t think it, but seeing this room, that overturned chair and upset telephone, in connection with the shooting, as you heard it, Mr. Brice, it certainly seems ominous. And most mysterious! Two people quarreling, a shot fired by one or other of them, and no sign of the assailant, his victim, or his weapon!

But until we can prove that, we must continue our search.” “Yes,” I agreed, “search for Mr. Gately and also, search for the man who was here and who quarreled with him.” “Or the woman,” insisted Norah. “I can’t think it was a woman,” I said. “Although the shadow was indistinct, it struck me as that of a man, the motions and attitudes were masculine, as I recall them. The hatpin may have been left here this morning or any time.” “The visitor must be found,” declared Mr. Talcott, “but I don’t know how to go about it.” “Ask the elevator girls,” I suggested; “one of them must have brought the caller up here.” We did this, but the attendants of the three elevators all denied having brought anyone up to Mr. Gately’s offices since the old man and the elderly lady who had been mentioned by Jenny. Miss Raynor had been brought up by one of the girls also, but we couldn’t quite ascertain whether she had come before or after the other two. While waiting for Miss Raynor to come again, I tried to do a little
