The old man stretched out his hand, as if to ring; but no bell was near. His eyes wandered wildly.

Then it stood clearly before me that I had nearly frightened the life out of him, and I at once became calmer.

"Be sensible, sir, and take the matter quietly. It was imprudent of you to buy the diamond, but we all know, of course, that you did it in good faith. But it will be necessary that you give a truthful account of how you got it, and from whom. If not, it may become a disagreeable business for you. That you can well understand."

"I only understand that I have bought the diamond from a young lady and given five thousand kroners for it. She did not ask for more," said the old man, trembling, while his eyes began to look brighter. "When you say it was not Miss Frick, perhaps, after all, it was not she; but then it must have been the other young girl in the house. I believe they call her Evelina. Yes, it was she, if you absolutely must know it."

"Well, that is far more probable, sir," I said encouragingly, for I felt a little ashamed of my violent conduct to the old man, "and you must excuse me if I was a little rough with you."

I rang myself for the servant, and with him as a witness, I gave the lawyer a receipt for the tortoise, which I took with me, and left.

The superintendent was not a little surprised when I put the diamond before him on the table; and when I had given my report, he congratulated me at the result, and complimented me on the manner in which I had conducted the affair.

I found it unnecessary to mention Jurgens's wretched attempt to prove that it was Miss Frick who had sold him the diamond.

The superintendent did not lay much stress on the part Jurgens had played in the matter.
