Dan had no answer for the question. “It must have been there when we started shooting,” he said slowly. “Probably we didn’t notice.”

“Maybe it’s one of Mr. Holloway’s arrows. Or worse luck—from Ross’ bow.”

“Could be,” Dan agreed as they picked up their arrows and left the range. “All the same, I wonder—”

His gaze roved toward the surrounding woods.

“You wonder what, Dan?”

“I don’t believe that arrow was shot by any of the Cubs or Mr. Holloway either,” he announced with sudden conviction.

Midge stared at him in amazement.

“Who else could have shot it, Dan?”

“Well, I don’t know,” the other boy admitted lamely. He was reluctant to tell Midge about the fire inside the castle until after he had talked with Mr. Hatfield.

“You’re keeping something to yourself,” Midge accused.
