But on neither could we detect any wound, nor was there anything to show the cause of death. I examined the hand of the woman, a tiny, slim, cold hand, the contact of which thrilled me by its chilliness, and saw that her rings, set with emeralds, rubies and diamonds, were of the finest quality.

“She’s beautiful,” Patterson observed, gazing down upon her. “Perhaps she was his wife.”

“Perhaps,” I said. “Curious that they should have both died together in this manner.”

“They were evidently sitting here chatting before dinner, when both were either murdered, or died suddenly before assistance could reach them. She died before he did.”

“What makes you think that?” I asked quickly, my eyes wandering around the large, comfortable room, the atmosphere of which was heavy with fragrant odours.

“Because he placed that cushion beneath her head,” answered the shrewd, observant police-officer. “He had kissed her, and she was in the act of smiling at his last act of love when her heart suddenly failed, and soul and body parted.”

“And he died immediately afterwards, you think?”

“Yes, that’s what I surmise. What’s your opinion?”

“I can form no theory at present,” I answered, bewildered. In the course of years spent in the investigation of crime for journalistic purposes I had had my wits sharpened, and rather prided myself upon the soundness of the theories I propounded in the articles I wrote. Patterson knew this, and probably for that reason had invoked my companionship in this curious affair.

Together we made a searching examination of the whole room, but there was absolutely nothing to show the motive, or even the mode, of the tragedy. The absence of servants was of course extremely suspicious, but neither of us attached much importance to that. A close examination of the scene was our present object, experience having taught that upon the scene of most crimes there remains some trace of the assassin. The old saying that “Murder will out” is truer than the majority of people believe, for even that night we had had a striking illustration in Patterson’s attention being attracted by the snake in the gateway.
