“Looks as though we ought to be able to bring ’em to justice sometime soon.”
“But when you come to think of it, Kit, we haven’t got a single thing that would really convict anybody of anything.”
She looked puzzled and distressed. “That’s true,” she had to admit. “Just because some Bayshore Bakery bread was found on that sub, and because we saw a nailed-up box on a trash barge doesn’t prove anything about ‘who dunnit.’”
“And just because there’s an easy way to climb this pine that has a seat at the top doesn’t prove that anybody on this island is a spy.”
“Of course boys have been building seats in trees for hundreds of years. Maybe it was old Uncle Mose’s young ‘Massa’ when he was last here.”
“Not very likely. That seat was put up there so recently that the nails aren’t even rusty—and you know that doesn’t take long in this salty air. And what’s more, there’s a boarded up shield on the side toward the Marine Base. It’s so cleverly camouflaged you’d hardly know it from the ground—see.”
Only after Brad pointed it out did Kitty see the brown painted wood in the thick upper branches.
“If they are using light signals for subs out at sea the Coast Guard would surely see them from the beach,” said Kitty.
“They probably don’t use lights, but some other signal code.”
They walked slowly toward their landing place and Kitty let Billy run ahead to join her father and Hazel.
