"Sarcasm never worries me," said the colonel. "I'm always getting into trouble, and I'm always getting out again. Give a dog a bad name and——"

He stopped. There arose in his mind a mental picture of a man swinging in an underground kitchen, and in spite of his self-control he shuddered.

"And hang him, eh?" said Sir Stanley. "Now, I'm going to put matters to you very plainly, colonel. There have been three or four very unpleasant happenings. There has been the death of the chief witness for the Crown against you; there has been the death of this unhappy man White, who was closely associated with you in your business deals, and who had recently broken away from you, unless our information is inaccurate; there is the death of Raoul, who was seen seated next to you and apparently carrying on a conversation behind a fan."

"He never spoke a word to me," protested the colonel.

"And we have the disappearance of Miss White, which is one of the most important of the happenings, because we have reason to believe that Miss White, at any rate, is still alive," said Sir Stanley, taking no notice of the interruption. "Now, colonel, you may or may not have the key to all these mysteries. You may or may not know who your mysterious friend, the Jack o' Judgment——"

"He's no friend of mine, by heaven!" said the colonel, and neither man doubted that he spoke the truth.

"As I say, you may know all these things. But principally at this moment we are anxious to secure authentic news concerning Miss White. Both I and Mr. Stafford King have particular reasons for desiring information on that subject. Can you help us?"

The colonel shook his head.

"If by spending a hundred thousand pounds I could help you, I would do it," he said fervently, "but as to Miss White and where she is, I am as much at sea as you. Do you believe that, sir?"

"No," said Sir Stanley truthfully; "I don't."
