He moved down to the end of the vault, spent a moment or two over the safe’s dial; and, as this door in turn was swung open, Billy Kane caught a glimpse of the tiers of plush-lined trays that held the famous ruby collection, and of the score of packages of banknotes that lay neatly piled in the compartments inside the safe.

Again David Ellsworth called out a series of numbers, and as before tested the new combination; and then, from beside the open door of the safe, he spoke abruptly:

“Before I lock up again, Billy, what about our friend Laverto? You went down there this afternoon, I believe?”

“Yes,” Billy Kane answered—and frowned. “But there’s no hurry about it, is there? I’m bound to confess that his story seems to be straight enough, and that I can’t find anything wrong, but——”

David Ellsworth chuckled suddenly, as he reached inside the safe and took out a package of banknotes.

“You’ve been laughing at me up your sleeve for fussing around with those combinations, my boy—I know you have. But you’re the old woman of the two, Billy. If you couldn’t find anything wrong, I guess everything is all right. If it isn’t”—he chuckled again, as he closed and locked the safe—“it would do my heart good to see someone put something over on you!”

The light in the vault went out. The vault door was closed and locked, the outer door shut, the portières drawn back into place, and David Ellsworth, coming back across the room, dropped the package of banknotes on the desk.

“Take ’em to him, Billy,” he smiled; “and take ’em to him now. He’ll have twelve hours more joy out of life than if you waited until to-morrow morning.” He picked up the card upon which Billy Kane had written the combinations, and placed it in his pocket. “You’ve got a better memory than I have, Billy,” he observed, “and I guess you’ve got this down pat now; but I’m afraid I’ll have to study the memo over a few times before I take a chance on destroying it.”

Billy Kane was paying little attention to the other’s words; he was riffling the banknotes through his fingers—they were of all denominations, from hundred-dollar bills down to fives. It was, in fact, a package of loose bills that he remembered having counted that morning.

“Do you happen to know how much there is here, Mr. Ellsworth?” he inquired abruptly.
