"Nothing just now.

But I guess he is up to something." Keeping well out of sight behind the hedge, the two boys watched the son of the money-lender.

"I think I know what he is up to," murmured Dave.

"Come on after him, Phil." As silently as shadows Dave and Phil followed the money-lender's son to the shed.

Once Nat looked around to see if the coast was clear, and the followers promptly dropped down behind a lilac bush.
