“Good night!” Chet exclaimed. “Perhaps mine are gone too.” He ran out of the shed over to the road and hastily examined the tool box on his machine. Then he straightened up with an audible sigh of relief. “Thank goodness, they’re here! Guess whoever took the others figured he had enough.” “I’m going back!” declared Frank. “If you do, you’ll have to excuse me,” Chet said. “You’re welcome to use my tools to fix up your machine, but I won’t go back with you.” “Me neither,” chimed in Jerry and Biff simultaneously. Frank and Joe were silent. They wanted to go back to the Polucca place and investigate the matter further, but they did not want to break up the party, so they decided it would be better policy to remain with their companions. “All right,” Frank said. “Lend me a pair of pliers and I’ll have this trouble fixed up in no time.” He went over to Chet’s motorcycle and got the desired tools. Then he began to tinker with his machine. It was only a minor defect, and a few minutes’ work sufficed to repair the damage. In the meantime it was apparent that the rain was letting up, and by the time the Hardy boys took their motorcycles out of the shed and regained the road, it had died away to a mere drizzle. “This has been some holiday!” Chet muttered, as he mounted his machine again. “I’m going home. Jerry, you and Biff had better come up to our place for dinner. How about you and Joe, Frank?” “Thanks just the same, but we couldn’t. We promised to be back home this afternoon.” “There’s a side road that turns off here that makes a nice short-cut to our farm. I guess I’ll go that way. There should be room for three on this bike, with a little crowding.” Jerry and Biff Hooper clambered on the motorcycle with Chet Morton and started off. The Hardy boys followed on their own machines until they reached the side road, about a hundred yards away. There the others left them, after shouting good-bye. Frank and Joe watched Chet’s motorcycle, heavily loaded, disappear into the mists that hovered over the road, and then they prepared to continue their journey back to Bayport. The shore road dipped at that point and wound down along the edge of the bay in a deep spiral, which brought them at one point almost back to the cliff at the top of which the Polucca place was located, although by now they were nearer the water’s edge. From there the road sloped directly down to the shore, then ran along the edge of the bay and in toward the city. Frank looked up toward the top of the cliff that loomed high above them. They could not see the Polucca place from where they were, as it was on the high ground and almost masked by trees, but the mystery of the place still preyed on their minds. “I’d like to go back there yet,” said Frank suddenly. “That affair of the tools has me guessing.” “Me too. But I think we’d better go on home. We can come back some other time and look for them.”
