Billingsgate Shoal

First, a fishing trawler runs aground on the Massachusetts shore. Then a young scuba diver sent to investigate the wreck is found dead in the water. Doc Adams, a friend of the dead diver, sets out through the stormy seas and blood-flecked sands of Cape Cod to plumb a murder he should have prevented. There he uncovers a hidden treasure in illegal arms and is nearly killed in the process. Doc lets the world think he's dead, the better to hunt for the killers of his friend. But if he makes a single mistake, he'll be clam chowder.
