To the surprise and also the consternation of Frank, he found that Jerry had noticed his manner, and he immediately accused the other.
"I can guess easily enough what you're thinking, Frank," asserted Jerry, with offended dignity marked in his manner; "but 'tisn't so, I tell you. I never set eyes on that old cup before he snatched it up out of that hole."
"No need of your saying that, Jerry," declared Frank, "because I believe you are as innocent as I can be myself. I only happened to remember that you talked of wanting to sneak up there and spy around a bit, though you owned it would be mean. And I also chance to know that you've been around every hour since you came back from the village."
"I'm blessed if I can make head or tail out of the game," admitted Jerry. "I never was a good hand at guessing answers to riddles; and say, let me tell you this thing is the toughest nut to crack that ever came our way, eh, Frank?"
"It's going to bother us a heap, that's right, Jerry."
"But somehow I've got my little hunch, Frank, that in the end you'll hit on the answer. It may take a lot of time and figuring, but I sure believe you can do it."
"It may be Gilbert can help us out," suggested Will, just then.
"But how would he know anything about the job," objected Bluff, "when he just got back from that golf tournament?"
Frank bent down and looked closely into the hole.
"All we know for certain is that somebody put that gold trophy cup in here," he observed reflectively.
