"Keep your eyes on them," said Forrest, "so. Now, we will suppose that you have good reason to believe that I have stolen your horse. Call me a horse thief."

"Sir," said the earl, entering into the spirit of the game, "you are a horse thief!"

There appeared in Forrest's right hand, which had seemed empty, which had seemed not to move or to perform in any celeritous and magic manner, a very small, stubby, nickel pistol, with a caliber much too great for it, and down whose rifled muzzle the earl found himself gazing. The earl was startled. But he said, "I was mistaken, sir; you are not a horse thief." As mysteriously as it had come, the wicked little derringer disappeared. Forrest's hands remained innocently in plain view of all.

"Oh," said Alice, "if you had only pulled the trigger!"

Evelyn giggled.

"Frankly, Mr. Forrest," said the earl, "aren't the twins loathsome? But tell me, can you shoot that thing as magically as you play tricks with it?"

"It's not a target gun," said Forrest. "It's for instantaneous work at close range. One could probably hit a tossed coin with it, but one must have more weight and inches to the barrel and less explosion for fine practice."

"What would you call fine practice?" asked Stephen.

"Oh," said Forrest, "a given leg of a fly at twenty paces, or to snip a wart from a man's hand at twenty-five."

Mr. Ballin rose.
