A woman named Maria Gomez is murdered in Miami, apparently by her husband--who'd been presumed dead, slain by a crime boss. FBI agent Brett Cody can't believe it; dead or alive, the man had loved his wife. Brett also can't help feeling guilty, since he was responsible for protecting Miguel and Maria Gomez. A few miles away, Lara Mayhew has just begun working at a dolphin research facility. She loves her new job--until a dolphin brings her something unexpected from the deep: a human hand. More body parts show up, and when Brett looks into the situation, he discovers that the dismembered corpse is Miguel's.
