As my old readers know, the place referred to was a dilapidated structure of brick and stone which had been erected about the time of the Revolutionary War. It set back in a wilderness of trees, and was given over largely to the owls and to tramps. It belonged to an unsettled estate that had gone into litigation, and there was no telling if it would ever be rebuilt and occupied in a regular way.
It was dark under the trees, but by pulling close to the boat ahead, Dave and Roger managed to keep Shadow Hamilton in sight. As soon as the somnambulist came near to the castle he ran his boat up the bank, leaped ashore, and stalked toward the building.
"He has disappeared!" cried Roger, softly.
"I see him," answered Dave. "Come!" and he led the way into the old structure and to the very rooms where the encounter with the robber and with Billy Dill had occurred.
Scarcely daring to breathe, they watched Shadow move around in an uncertain way, touching this object and that, and opening and shutting several closet doors, and even poking into the chimney-place.
"Gone! gone! gone!" they heard him mutter. "What shall I do? What shall I "do?" And he gave a groan.
