There was a dead pause. Denny looked hard in Kane's face. "Yes," he said, "she was. She came there to try and prevent our quarrel." The men who had seen the moving-picture of the shadow breathed again.

"What did she do when you fired?"

"I sent her down to the Deutches to get a doctor. I wanted her out of the way, and I switched off the lights so she need not see how useless any doctor was!"

"How did you yourself escape?"

"Up the back stairs, across the roof, into the next house."

"But she went out of the room before you did?"

The earth swam before Herrick's eyes, and then he heard Denny's "Yes."

"Then since you were the last to leave, explain how you were able to bolt the door behind you?"

"I didn't bolt it behind me. I stayed in the room."

Herrick lifted his head.
