asked.
âNot that,â Frank said.
Joe listened again, harder this time. âRunning water. The river. Sounds pretty close. I didnât notice it before.â
âLetâs go,â Frank said.
The wolf-dog didnât prevent them from reaching the water. Kendall River was about twenty feet wide and ran swiftly, babbling over numerous rocks and small boulders.
âGood whitewater, if itâs deep enough,â Joe said.
âMm,â Frank said. With his eyes, he was tracing a line of boulders that crossed the river. âHey, Joe,â he said, pointing. âWhatâs that look like to you?â
Joe looked where Frank indicated. In the woods nearby a large configuration of jumbled rocks cropped up out of the ground. From where the Hardys stood, the rock formation looked like the profile of a huge bird.
âWow,â Joe said. âIâd say that must be Eagle Rock. According to the information Chelsea gave me, the eagleâs head is supposed to point toward the Cave of Chaos.â
Frank squinted and peered into the woods. âI think I do see a large rocky mound that way,â he said. âLetâs try it. Keep an eye on that wolf, though.â
The Hardys cautiously made their way through the woods to the rock mound. It jutted out of the landscape like the back of a whale. Several smaller boulders lay beside its base, but to one side of the mound the brothers could see an opening just big enough for a person to squeeze through.
âThatâs it!â Joe said. âWeâve found it!â
Frank glanced back the way they had come. He didnât see anything, and when he listened, all he heard was the faint singing of birds. âI think our wolfish friend has given up on us,â he said.
âYou know,â Joe said. âWe ought to thank that wolf. If we hadnât left the path, I doubt weâd have ever spotted Eagle Rock.â
Frank and Joe squeezed inside the opening. Just beyond the entrance, the cave opened up into a small âroom,â with one narrow passageway leading back deeper into the rock.
âDid you notice those boulders near the entrance?â Frank asked.
âYeah,â Joe replied. âLooked like theyâd been moved recently: the ground around them was disturbed and the moss was growing on the wrong side of them. What I wonder is, who moved them and why?â
âMaybe to open up the entrance to the cave. Those boulders could have prevented anyone from discovering it,â Frank said.
âI suppose one guy could have moved them with a decent lever,â Joe said.
âRoyal, you mean,â Frank said. âThe question now is, is there anything in here, or is he just leading us on a wild-goose chase?â
âOnly one way to find out,â said Joe. He pulled his flashlight from his backpack and switched iton. Then he and Frank ventured into the passageway beyond the room.
âLooks like a glacial cave,â Joe said, running his hand over one rough wall. âFormed by the movements of rocks during the last ice age.â
âYeah,â Frank said. âNothing like Carlsbad, or the Cave of the Mounds. No stalactites or stalagmites. Pretty big for a glacial system, though.â
âNot too big, I hope,â Joe said. âIâd still like to get out of here before dark. Hey, Frank, Iâve been thinking.â
âYeah?â
âAbout something Chelsea said earlier. Didnât she mention the ghost of Katherine Chaosâs sister being in the new game?â
âI think so,â Frank said. His eyes lit up. âAre you thinking that maybe McLean isnât so crazy after all?â
Joe nodded. âWe know that she couldnât have seen a ghost, but maybe she did see someone who looked like Sakai.â
âA relative, you mean,â Frank said. âI wonder if Regina Cross is related to Sakai. Usually peopleâs heirs are their
