Oh how charming! This is the kind of Miss Pickerell book I loved as a child. Sure, nowadays interested kids know all about radar vs sonar, starboard, the bends, coral formed by skeletons, etc. - but back in the day this was a great way to learn stuff and feel smart. And what a role model! She's just a quiet country Auntie, but give her enough motivation and she'll go to Mars, mountain-climbing, or undersea! ( )

I think this was the first Miss Pickerell I read, and my favorite. After 50 years I still remember how it seemed the bad guys had claimed salvage rights on a wreck, but because Miss Pickerell had retrieved a wristwatch from the wreck for a friend, that counted as salvage and the good guys got the wreck. Even in my youth I appreciated neat points of law. ( )
