“Robin Hood’s strong box,” Dan repeated, recalling the Castle chimney niche which had been given that name. “Well, what do you know!”
“This message seems to make sense to you, if not to me,” Mr. Kain said testily. “Will someone kindly explain what is meant by Robin Hood’s strong box?”
CHAPTER 16
Treasure
The Cubs were reluctant to tell Mr. Kain their secret, lest he feel that they had overstepped themselves in investigating the Castle.
“Robin Hood’s Strong Box is just a name for a hiding place,” Dan explained vaguely.
“Then one of you boys shot this arrow.”
The Cubs looked from one to another. Each boy shook his head.
“A mysterious archer has been annoying us a bit by shooting arrows during our rehearsals,” Mr. Hatfield explained. “This shaft looks as if it may have come from his bow.”
“But how did he know about Robin Hood’s Strong Box?” Midge muttered. “The guy must be psychic. Either that, or he sneaks around listening to our conversation.”
“I am quite certain this arrow was not lying near my car when I drove into the grounds today,” Mr. Kain said. “It has been shot in the last hour or so.”
