"What is it?" he asked again.

"I must apologize for intruding, but I thought it best to approach you before making my report to Sir Thomas."

"Your report?"

"I am employed by a private inquiry agency."

"What!"

"Yes, sir. Wragge's. You may have heard of us. In Holborn Bars. Very old established. Divorce a specialty. You will have seen the advertisements. Sir Thomas wrote asking for a man, and the governor sent me down. I have been with the house some years. My job, I gathered, was to keep my eyes open generally. Sir Thomas, it seemed, had no suspicions of any definite person. I was to be on the spot just in case, in a manner of speaking. And it's precious lucky I was, or her ladyship's jewels would have been gone. I've done a fair cop this very night."

He paused, and eyed the ex-policeman keenly. McEachern was obviously excited. Could Jimmy have made an attempt on the jewels during the dance? or Spike?

"Say," he said, "was it a red-headed—?"

The detective was watching him with a curious smile.

"No, he wasn't red-headed. You seem interested, sir. I thought you would be. I will tell you all about it. I had had my suspicions of this party ever since he arrived. And I may say that it struck me at the time that there was something mighty fishy about the way he got into the castle."
