"They are fine stuff," said I; "do you happen to know where they come from?"

I looked him full in the face when I spoke, and observed a slight drawing of the lines above his mouth. When he answered me I was sure that he had thought out a lie—and with effort.

"I believe they come from Salzburg," he stammered; "at least I have heard so."

"That could not possibly be," said I; "the worst emeralds we have are the best product of that mine. I fancy they are from Venezuela."

"Ah, that's the place," said he, "I remember it now; but I've a wretched head for geography."

While he said this the train to London steamed out of the railway station, which is not a stone's throw from the inn, and he, forgetful of his tale to me, sat watching it unconcernedly. I had discovered him in a second lie, and I waited to entrap him to a third with the practised pleasure of a cross-examiner.

"Do you sell these stones for yourself or as an agent?" I asked, assuming some authority as I felt surer of him. His hesitation in answering was merely momentary, but it was enough for my purpose.

"For myself," said he; and then with clumsy maladroitness he added, "They were left to me by my father, and I have never had the heart to offer them to any one. I'll tell you what, though; if you'll give me a thousand pounds for the pair, you shall keep them."

"That's a long price," said I; "and if you don't mind the suggestion, my dinner's getting cold."

I had spoken thus with the design of putting him off; but he was undisguisedly an ill-bred man, and I saw that I could have bought the emeralds from him for five hundred pounds. My hint—if such you could call it—fell upon deaf ears; and he, seeming not to hear it, continued to argle-bargle, but betraying himself in every word he said.
