“I was afraid to do anything but follow your instructions,” she said earnestly. “I remembered that you swore you’d put my sister in prison if I even said I’d ever seen you before.”

“Well, then, we won’t say any more about it,” he returned ungraciously. “How did you find Denby had the necklace?”

“I got into his room and caught him,” she explained. “He had it in his hand.”

“Yes, yes!” he cried impatiently; “go on.”

“And when the lights went out and there was a shot, I screamed, and naturally I couldn’t see what happened in the dark. I thought you had killed him and I was frightened.

Taylor frowned. He did not like to remember that directly the flash of his gun had disclosed his position Denby had sprung on him like an arrow and knocked him down. Denby had scored two knock-downs in one night, and none had ever done that before. There was a swelling on his jaw and three teeth were loosened. Denby should pay for that, he swore.

While he was thinking these vengeful thoughts, Duncan hurried in through the French windows.

“Say, Chief,” he shouted, “Denby didn’t leave the house. He’s up in his room now.”

“How do you know?” Taylor cried eagerly.

“Gibbs climbed up on the roof of the pagoda; he can see the room from there and Denby’s in it now.”
