“What's that?” said Hope sharply. “Why did you—oh, gosh!” He jumped up with an amazed look as Random held up the magnificent gem, from which streamed vividly green flames in the mellow lamplight. “Oh, gosh!” gasped the artist again. “Where the devil did you get that?”

“I sent for you to tell you,” said Sir Frank, giving the jewel into his friend's hand and coming back to his seat. “It was found in the sentry box.”

Hope stared at the great jewel and then at the soldier.

“What do you mean by that?” he demanded. “How the dickens could it be found in a sentry box? You must be making a mistake.”

“Not a bit of it. It was found on the floor of the box by the sentry, as I tell you, and I have sent to consult with you as to how the deuce it got there.”

“Hervey,” muttered Archie, fascinated by the gem.

Random shrugged his square shoulders.

“Catch that Yankee Shylock returning anything he got his grip on, even as a wedding present.”

“A wedding present,” said Hope, more at sea than ever. “If you don't mind giving me details, old chap, my head would buzz less.”

“I rather think that it will buzz more,” said Random dryly, and, producing the brown paper in which the gem had been wrapped, and the inscribed paper found within, he related all that had happened.
