The switches were just outside the door. As she stretched out her hand to them, the incredible thing happened. Suddenly without any warning, every light was extinguished, the door banged, and from the other side of it came a long-drawn piercing woman’s scream.
“My God!” cried Lord Yardly. “That was Maude’s voice! What has happened?”
We rushed blindly for the door, cannoning into each other in the darkness. It was some minutes before we could find it. What a sight met our eyes! Lady Yardly lay senseless on the marble floor, a crimson mark on her white throat where the necklace had been wrenched from her neck.
As we bent over her, uncertain for the moment whether she were dead or alive, her eyelids opened.
“The Chinaman,” she whispered painfully. “The Chinaman—the side door.”
Lord Yardly sprang up with an oath. I accompanied him, my heart beating wildly. The Chinaman again! The side door in question was a small one in the angle of the wall, not more than a dozen yards from the scene of the tragedy. As we reached it, I gave a cry. There, just short of the threshold, lay the glittering necklace, evidently dropped by the thief in the panic of his flight. I swooped joyously down on it. Then I uttered another cry which Lord Yardly echoed. For in the middle of the necklace was a great gap. The Star of the East was missing!
“That settles it,” I breathed. “These were no ordinary thieves. This one stone was all they wanted.”
“But how did the fellow get in?”
“Through this door.”
“But it’s always locked.”
