"Mr. Overton!" called Captain Foster gasping.

But Hal did not have to be summoned. He had heard Ruggles's last statement from the doorway of the officers' tent.

"Here I am, sir," cried Lieutenant Hal, coming forward, "and I overheard that lying hound! What this fellow, Ruggles, is telling you, Captain, is wholly false."

"I know it, Overton, I know it," cried Captain Foster, who had sprung to his feet.

"Am I to be flimflammed, after paying the money in good faith?" demanded Ruggles. "See here, Captain, I drew twenty thousand dollars, in twenty bills, at the bank this afternoon. That I can easily prove, of course. Nor can any one on earth prove that I have spent any of that money, for, as it happens, I had the cashier at the bank take the numbers of the thousand-dollar bills. In this envelope, sir, you will find fifteen of the bills left. The numbers of the missing bills can be proved, and the missing bills you will find in the possession of your lieutenant."

"It's a cowardly lie!" blazed thunderstruck Hal, leaping forward. But Captain Foster pushed him gently back.

"I haven't a doubt that it's a lie, Overton, my boy," replied Foster. "Yet don't get too excited, or try to use violence on your accuser. Remember that I am simply bound to hear any complaint that may be preferred against any officer in my command. Be cool, Overton, and be sure that no harm can come to you if you are innocent, as I am certain that you are. Here is your envelope, Mr. Ruggles. I have looked over the contents, which are, as you state, fifteen one-thousand-dollar bills."

"And the other bills you will find on this lieutenant. Though, wait a moment. He has just been in his tent. He may have hidden the money there."

"If it's true that you handed this lieutenant money, Mr. Ruggles, what did he do with it when he first received it?" asked Foster.

"I don't know, Captain, except that he went forward into the stateroom to look it over. He didn't have it in his hand when he came out of the stateroom."
