In Cujo, Bannerman helps organize the search for Donna and Tad Trenton, who are currently missing, and unbeknownst to anyone, trapped at the Camber house by the titular rabid Saint Bernard.

Suspicious when there are no leads to their location and inspired by his previous investigation with Smith and the Dodd case, Bannerman checks at the Camber house and discovers Donna and Tad.

Appeared in the novel Cujo (1981) and portrayed by Ed Lauter in the film adaptation of the same name (1983), Joe is an alcoholic, controlling man who frequently abuses his wife Charity and is generally hostile to everyone around him; the only two exceptions are his son Brett and his friend Gary Pervier.

Alan and Polly are also briefly mentioned in Bag of Bones (1998) in a conversation between author Michael Noonan and the then-Castle County Sheriff Norris Ridgewick.

[7] John "Ace" Merrill is a psychopathic, cruel bully who appears in "The Body", "The Sun Dog", "Nona", and Needful Things.

In "The Body", Ace is the leader of some bullies who torment Gordie Lachance, Chris Chambers, Teddy Duchamp, and Vern Tessio.

By the time of "The Sun Dog", Ace has been sent to Shawshank State Penitentiary and disowned by his only remaining family, his uncle Pop Merrill.

Reginald Marion "Pop" Merrill is a loan shark and the owner of the Emporium Galorium, a local junk store, who appears in "The Sun Dog" and is mentioned in Needful Things.

In spite of this, Pop is extremely wealthy and well-connected and serves a variety of clients, from desperate people he takes advantage of to renowned billionaires.

Needful Things shows that the reason for Pop's death is unknown to the general public, though everyone, even his nephew Ace Merrill, is happy that he is dead.

Gaunt later convinces Ace that Pop had buried part of his fortune to gain his assistance and cause a feud between him and Sheriff Pangborn.

On the morning they are supposed to leave for Boston, Joe's rabid Saint Bernard Cujo attacks Gary while he is going through a hangover in his yard.

After Dodd murders a nine-year-old girl, who is found in the same location as his first victim, Bannerman brings in psychic Johnny Smith to assist in the investigation.

When Cujo attacks Sheriff George Bannerman, he imagines that the dog is possessed by the ghost of Dodd, and mentally inquires if he came back because Hell was too hot for him.

No one notes much significance to the wound, but as it festers Cujo becomes depressed and occasionally ill-tempered (people think he's just bothered by the summer heat or, as observed by two delivery men, "going bad"), then goes mad.

After murdering Joe Camber and Gary Pervier, Cujo traps Donna and Tad Trenton inside their broken-down car after they come for auto repairs.

In Needful Things, Polly Chalmers, while at the now-abandoned Camber home, encounters Cujo's malevolent and restless spirit, which chases her out of the farm.

He reappears as a main character in Needful Things, being one of those manipulated by Leland Gaunt into helping him drive the town into chaos.

Ridgewick was portrayed by Zachary Mott in The Dark Half, Ray McKinnon in Needful Things, and Timothy John Smith in the television series Castle Rock.

Danforth "Buster" Keeton is the cruel, hot-tempered, and mentally unstable town selectman, who appears in The Dark Half and Needful Things.

[30][31] Director Rob Reiner later named his production company Castle Rock Entertainment, which subsequently produced several adaptations of King's works.
