“I’ll tell you why, son,” was the answer, “it was because I have always feared this Rod Marbury! I’ve feared him ever since he and Jolly Bill tried to bilk old Hank—not that Bill started that plan—it was Rod. But I knew from that he was a desperate man, though Jolly Bill got the worst of the deal—he lost a leg and the fortune that had been his, while Rod only lost the money. But now he’ll get it all—that’s the way in this world—the wicked sure do flourish like a green bay tree, as the Good Book says, and many’s the bay tree that I’ve sat under, though I never thought, at the time, I’d have this bad luck.”

“Maybe it will turn out all right,” suggested Bob, hopefully.

“I’m afraid not,” was the gloomy answer. “Anyhow, as I was telling you, I built this strong room in my cabin after I heard what Rod had tried to do to Hank. I thought my turn would come some day, and it did—but not as I planned. It was the first time I ever went in my strong room, to do anything, without locking the door behind me. If I had done that Rod couldn’t have gotten in. But I figured that after he got fooled on the road he wouldn’t try again. But he got in, and of course, after that, it was easy for him to get out, after locking me in.”

“But how did he get the key back in?” asked Bob. “That’s the secret of this log cabin that I’d like solved.”

“I’ll never tell you,” said old Hiram with a shake of his head. “Any more than I can tell you what made those funny marks, like a sack of potatoes.”

“Well, that’s what I’ve got to work on,” decided Bob. “I’ve got to discover the secret of the log cabin, and locate Rod. But you might help in the last.”

“How?” asked Hiram.

“By giving me some idea of where he might start to dig for the hidden treasure—telling me the probable location of the place where Hank Denby might have hidden it.”

Hiram Beegle shook his head dubiously.

“Might as well try to look for a needle in a hay stack,” he said. “Hank was a strange man. He’d pick out a hiding place you nor I would never dream of. He must have taken a leaf out of the book of the old pirate who originally had this money. How he got it—I mean how the pirate came by the wealth—no one knows. Perhaps it’s just as well not to inquire. Anyhow the real owners couldn’t be found after all these years. And I intended doing good with the money after I got it. I was going to leave most of it to a hospital.”
