The Den Chief stooped to pick up the charred arrow which Mr. Kain had dropped on the grass. Carefully he studied it.
“You think that may have significance?” Dan asked after a moment.
“Maybe so. Maybe not. The arrow could have been lying out in the woods a long while. We know our mysterious Robin Hood has shot plenty of them.”
“Say! That’s an idea, Brad!”
“What is?”
“Maybe the fire was started by the fellow who has been roving around here—the Ghost of the Castle!”
Brad smiled, for the thought had occurred to him when first he saw the charred shaft.
“We know the Ghost is a very real person,” he commented. “We also know he roams over this property and the Castle at will.”
“He could be a tramp.”
“I’ve thought the same thing, Dan. We certainly shouldn’t blame Ross for that fire, until we’ve made as complete an investigation as possible.”
