The cover artwork shows a werewolf on a couch with a remote control in its hand.
Aaron Freidus and his father are hunters, who capture an innocent man named Ben who may be a werewolf that has terrorized the town. But when Aaron begins having dreams of bloodshed and death, he discovers that he could be the culprit.
However, Aaron's best friend Ashley tells him that Ben could not be the werewolf. Aaron releases him, only to find the whole city terrorized by a werewolf.
Aaron thinks Ben is the culprit and curses him himself. Later he wakes up with a bloodstained body and realizes that he is the werewolf and was turned so, once after he was bitten by a wolf. Once his father finds out, he wants to send him to prison forever. But to save himself, Aaron bites his father, turning him into a werewolf.
- In France, this book is the 60th of the original Goosebumps series. The title was translated "Un loup-garou dans la maison !", which means in English "A werewolf in the house!", and the tagline was changed into "Morsure fatale" (A deadly bite).
- Aaron Freidus shares a name with a character in Jekyll and Heidi.
- Illustrator Tim Jacobus believed that the werewolf's skin — as it appears on the cover of this book — would have been too grotesque an element to include on a cover in the original Goosebumps series.
