The story begins with an inheritance. Following a protracted legal battle, Alice St. Ives, Langdon’s wife, has come into full possession of Seaward, the house left to her by her late Uncle Godfrey, a man with a number of bizarre proclivities. Heartened by this good fortune, Alice, Langdon and their surrogate son Finn prepare to take possession of the house.

What follows is a tale of two houses. The first is Seaward, a “rambling, eccentric old house” with its history, its secrets, and its accumulation of volumes of arcane lore. The other is a neighboring house known as “Gobblin’ Manor,” home base of The Gobblin’ Society, a “culinary establishment” with its own peculiar—and very dark—traditions. In the course of an event filled few days, St. Ives and his cohorts will encounter smuggling, mesmerism, kidnapping, cannibalism and murder.
