"He is a gentleman, sir, who is interested in solving problems of crime. It's a sort of hobby with him, sir," said Jenkins, his usually somber eyes beginning to sparkle as he spoke.

"You mean that he is a private detective?" I asked, not overly pleased, for Jones of Headquarters had struck me as being up to snuff and yet every clue that he found had only drawn the net more tightly about Ruth. It was no wonder therefore that I was chary of detectives, for except in books, I deemed them all cut out of the same mold and after the same pattern.

"Oh, no, sir," returned Jenkins, horrified. "He's not a detective in the ordinary sense of the word. He is what you call an investigator of crime and he only takes cases that he thinks are worth-while solving. He does it mostly to amuse himself, sir."

"Oh, I see. A second Sherlock Holmes, eh?" I said ironically.

Jenkins looked hurt. "He says, sir, that there is no one who can equal Sherlock Holmes. He says, sir, that beside Holmes he's only an amateur burglar, though begging his pardon, I don't agree with him, sir."

"How does it happen that you know so much about him, Jenkins?" I asked suspiciously.

"He once saved my life in the Great War, and in return I help him with his cases when he needs me, sir."

"Humph. I thought I employed you, Jenkins."

"Well, yes, sir. But I have my free hours, sir." The poor fellow's face grew so very mournful at my insinuation that I could not help smiling even in the midst of my despondency.

"I'm not blaming you, Jenkins. I was merely wondering why he didn't hire you altogether," I said.
