He stepped toward the foxy little man but:

“Never mind, Gray,” interrupted Irvin. “I was to blame. But he was following my wife, not you. Tell me quickly: Why did she come here?”

Gray raised his hand to his brow with a gesture of bewilderment.

“To consult this man, Kazmah. I actually saw her enter the inner room, I went to get a cab, and when I returned the door was locked.”

“You knocked?”

“Of course. I made no end of a row. But I could get no reply and went away.”

Monte Irvin turned, a pathetic figure, to the Inspector who stood beside him.

“We may as well proceed, Inspector Whiteleaf,” he said. “Mr. Gray’s evidence throws no light on the matter at all.”
