Nancy Drew #5: The Fake Heir

Nancy, along with Bess and George, find the wreck of an old yacht with a safe inside full of jewellery worth a small fortune. Cousins of the Druthers, who are clients of Nancy's dad Carson Drew, owned the yacht. Their will leaves everything to Mr Druthers, but no one's seen him for ten years and the rumour is that Mrs Druther has murdered him!
