Slade House

In 1979, Nathan Bishop and his mother are invited to the house of the respected Lady Grayer. Nathan is quickly acquainted with her son Jonah, and the two spend the afternoon in the garden of Slade House whilst Norah Grayer entertains Nathan’s mother. Nathan begins hallucinating strange people and other visions and becomes worried that the Valium he took from his mother is having a bad effect. After being invited into the house, he experiences more hallucinations before finding himself at his father's lodge in Rhodesia. This dream is quickly broken by the Grayers, who reveal themselves to be twin siblings and carnivorous Anchorites, beings who steal the souls of certain people to maintain their youth. The Anchorites conduct a ceremony, and feast on Nathan’s soul.

In 1988, a detective inspector, Gordon Edmonds, is investigating Slade Alley, and stumbles into the garden. There, he meets a widowed woman named Chloe Chetwynd. While they talk, Edmonds hears children playing but is confused to see there are none. Edmonds reveals he’s investigating the disappearance of the Bishops, who were assumed to have fled debts, but a window cleaner awakened from a coma revealed his interactions with them on the day of their disappearance. The inspector and Chloe strike up a relationship, and Chloe reveals that the voices Edmonds heard are ghosts she too hears. They become intimate, but it is short-lived. Edmonds is lured upstairs, and has a brief encounter with the remnants of Nathan. The twins reveal they are not members of the Anchorites, but act alone. Norah, to Jonah's disdain, believes they can no longer operate as they have. They begin their ceremony and absorb Edmonds' soul.

In 1997, a group of students belonging to a paranormal club converge upon Slade House, intending to investigate the disappearances of the Bishops and Edmonds. One of the students, Sally Timms, is infatuated with a fellow member. The leader of the group is the nephew of Fred Pink, the window cleaner who saw the Bishops before they disappeared. The group stumble into a previously non-existent Slade House and discover it appears as a student house in the throes of a Halloween party. Sally mingles with the guests of the party before waking to find herself next to a frozen man implied to be Inspector Edmonds, who hands her a weapon, a hairpin with a fox head. Sally is led to the attic via the Grayers' mind games. The twins argue once again about their methods, and prepare their ceremony. Sally swears someone will stop them, and then her soul is consumed.

In 2006, Sally Timms' sister Freya meets with Fred Pink in a pub near the supposed Slade House. Pink reveals he has been investigating the House and the Grayers for years. He tells her they were born in the late 1800s, and were known for their mystical abilities. They travelled the world learning all they could and eventually retired to Slade House in the 1930s. They used their power to isolate Slade House from time, placing it in a bubble where it existed long after its destruction during bombings in the 1940s. Freya, believing Pink to be mad, intends to leave, but finds herself in the attic of Slade House. Jonah reveals he was playing Pink all along. Norah is furious with him for revealing their history to Freya, but they begin their ceremony. Just as Freya's soul is taken from her body, Sally appears, stabbing Jonah in the neck with the fox pin. The twins are enraged, and Freya's soul is not consumed and allowed to pass on.

In 2015, Norah Grayer invites the former psychologist of Fred Pink, a Doctor Iris Marinus-Fenby, to Slade House. After eighteen years without fresh energy, the house's reality is decaying and Jonah remains injured and trapped in the attic. Norah inhabits the body of a young conspiracy theorist, who lures Iris into the garden with the insistence Pink was not mad. Within the reality of Slade House, it is clearly fading away, and a weakened Norah and Jonah are unable to play their normal mind games. Iris is drawn to the attic, where Jonah and Norah prepare to consume her, but at the last minute she reveals herself to be an Horologist: these are immortals who are reincarnated as opposed to the Shaded Way method of consuming souls for immortality. Marinus criticises the antiquity of the Grayers' methods compared to new ones, and encourages Jonah to attack, allowing her to easily destroy him. She leaves Norah in the collapsing attic of Slade House's final moments to age and wither into nothing. At the last second, Norah, enraged and powered by the desire for revenge, transplants her soul into an unborn child.
