Overview
Slugs is a 1982 UK horror novel written by Shaun Hutson. In 1988, it was adapted as an American/Spanish horror film of the same name. In this book, carnivorous slugs go on a rampage.
Synopsis
Slugs in the cellar of an old house feed on scraps of rotten meat someone is unknowingly throwing down to them.
A very drunk Ron Bell stumbles home, passes out in his front room and wakes to find himself being eaten alive by slugs that have come through the floor. The slugs then retreat back down the cellar.
Mike Brady, an almost-40-year-old council health inspector awakes with wife Kim, 35, and discusses that he has to help evict a council tenant Ron Bell that day. Brady accompanies Archie Reece, bailiff, to serve an eviction notice on Ron Bell. They find Bell's mutilated body. The slugs leave Ron Bell's cellar, crawl up into his garden and then down into the sewers towards a new housing estate.
