Riptide

For centuries, treasure hunters have sought the lost horde of the notorious English pirate, Edward Ockham. Clues led to the mysterious water pit on Ragged Island, Maine--but a curse left behind by the long-dead pirate still seems to be working. Every expedition has failed--with the treasure seekers dying in gruesome fashion. Now, however, a new expedition has been mounted with state-of-the-art computer technology and backed by millions of dollars. It will all be worth it if the treasure is found. But modern technology may not be enough to overcome the deadly secrets of the water pit.
