"I did not know," he said slowly, the most provoking manner, "that I had to do with a detective. What is the charge?"

"There is no charge," I answered, keeping my temper really admirably. "But I have seen the face of a friend of mine in that book, and I'll in a word, I'll be hanged, young man, if I don't learn all about it!" I continued. "All--do you hear? So there! Now, out with it, and do not keep me waiting, you young rascal!"

He only whistled and stared; and finding I was getting a little warm, I took out my handkerchief, and wiping my forehead, sat down, the thought of the Colonel's grief taking all the strength out of me. "Look here," I said in a different tone, "I'll take back what I have just said, and I give you my word of honour I do not want to harm the--the gentleman. But I have seen his portrait, and, if I know no more, must think the worse. Now I will give you a ten-pound note if you will answer three questions."

He shook his head; but I saw that he wavered. "I did not show you the portrait," he said. "If you have seen it, that is your business. I will name no names."

"I want none," I answered. I threw open the album at the tell-tale photograph, and laid my shaky finger on the face. "Was this sent to you that you might personate the original?"

He nodded.

"From what place?"

He considered a moment. Then he said reluctantly: "From Frome, in Somerset, I believe."

"Last year?"

He nodded. Alas! Jim had been at a crammer's near Frome. Jim had passed his examination during the last year. I took out the money and gave it to the man; and a minute later I was standing in the street with a sentence common enough at mess in the old days, ringing in my ears: "Refer it to the Colonel! He is the soul of honour."
