Three Skeleton Key

Three men who tend the light at a reclusive island off the coast of French Guiana see a rogue ship adrift in the Atlantic. The reason for the derelict ship soon becomes obvious – it has been overrun by hundreds of thousands of ferocious ship’s rats.
The rats land on the isle and soon we are in for a claustrophobic tale of terror as the three men struggle to keep their minds from cracking under the pressure of thousands and thousands of squeaking, scratching, hungry rats.
