"That the Jack o' Judgment is related to 'Snow' Gregory?" asked the colonel huskily.

"That is my suggestion," said the commissioner.

"And you think——"

The commissioner raised his shoulders.

"I think he is your greatest danger, colonel," he said, "far greater than the police, far greater than the clever minds which are planning to bring you to the dock and possibly," he added, "to the gallows."

Ordinarily the colonel would have protested at the suggestion in the speech, protested laughingly or with dignity, but now he was stricken dumb, both by the seriousness of the commissioner's voice and by the consciousness of a new and a more terrible danger than any that had confronted him. He rose, realising that the interview was ended.

"I am greatly obliged to you, Sir Stanley," he said clearing his throat. "It is good of you to warn me, but I'd not like you to think that I am engaged in any dishonest——"

"We'll let that matter stand over for discussion until another time," said the commissioner dryly, as Stafford King came into the room. "You might show the colonel the way to the street. Otherwise he will be getting himself entangled in some of our detention rooms. Good morning, Colonel Boundary. Don't forget."

"I'm not likely to," said the colonel.
