Plot
At the decaying Merrye House, feared by locals, the Merrye children Ralph, Virginia, and Elizabeth have lived in seclusion with the family chauffeur Bruno ever since their parents died. All three have advanced Merrye Syndrome, a genetic affliction unique to members of the family which causes them, starting in late childhood, to regress down the evolutionary ladder mentally and physically. They exhibit a playful innocence well before their years mixed with feral madness. Ralph is a sexually advanced, but mentally deficient simpleton who moves through the house via the dumb-waiter. Virginia is obsessed with spiders, and has more than once murdered visitors in a game of "spider", trapping them by rigging a window to snap shut on them before hacking them to death with butcher knives. Elizabeth is regarded by Bruno as the most responsible of the three, but is also conniving and infatuated with the concept of hate. The children hold a steadfast respect and affection for Bruno, but increasingly disregard his admonitions against their darker impulses.
Virginia's latest victim is a delivery man serving notice that Peter Howe and his sister Emily, distant relatives of the Merrye family, are coming with their lawyer Schlocker and his secretary Ann, seeking to claim the property as rightful heirs. Bruno hastily coaches the children in enough social etiquette to pass muster before the visitors arrive. Schlocker is outraged that the children have been in the sole care of Bruno (who did not acquire legal guardianship) and have never attended school. Bruno tells him the children are mentally retarded and resists the suggestion to put them in an institution, having sworn to their father to protect them for life. Emily and Schlocker insist on staying overnight to examine the situation, but with only two rooms available, Peter takes Ann into town to stay at an inn.
