Menace is everywhere as naval doctor Peter Crane investigates mysterious illnesses at an even more mysterious underwater research facility in the North Atlantic. The scientists say they're excavating long-lost Atlantis, but Crane suspects that something weirder and more dangerous is under way. Thank goodness for narrator Scott Brick, who offers both equanimity and tension in his reading, which intensifies the drama while keeping the complex plot clear (if not believable). He also adds color through subtle characterizations of everyone from straight-ahead military types to obsessed researchers and truly creepy secret agents.
