The undersea treasure

the long version

"A wreck lying on the bottom of the sea; a lawless smuggler and his accomplice; a family heirloom with a secret drawer; the chance to learn the science of underwater archaeology with a group of skin divers--what more could Mark want for a perfect vacation? "But when he went off for his summer holiday on an archaeologist's ketch, carrying with him, though he did not realize it, a clue to a secret treasure, Mark little dreamed what awaited him. The sand of the sea bed, the glitter of treasure, the drama of an ancient world called upon all of his varied talents as part scientist, part detective, and all skin diver. "THE UNDERSEA TREASURE is the first book for young people by Richard Garnett, son of David Garnett. It is an informative, tingling adventure story---a treasure every young would-be skin diver, archaeologist, detective, and boatsman will be happy to discover."
