Peter Benchley's Creature

At a small marine institute off the coast of Connecticut, only marine biologist Simon Chase realizes that a sixteen-foot pregnant Great White is feeding in the area. But even Simon doesn't know that a far deadlier creature is about to come out of the deep and threaten everything he cares for. A creature whose malevolence is unthinkable. Whose need to feed is insatiable. And whose relentless hunt for prey is unstoppable.
