The Deadly Grimoire

An Arkham Horror Novel

By Rosemary Jones

A daring actress and a barnstorming pilot team up to save the world from supernatural disaster in this uncanny pulp adventure set in the world of Arkham Horror.

Betsy Baxter is the plucky stunt-actor star of the 1920s serial adventure, The Flapper Detective. While researching a wing-walking scene, she meets the fearless Winifred Habbamock and discovers a shared background of eerie encounters and eldritch phenomena. For years, Betsy has been investigating the disappearance of an old friend during the horror-struck filming of The Mask of Silver, when she learns of his reappearance in Arkham, she and Winifred hit the road to investigate. But Arkham is full of mysteries and danger. Betsy will need all her skills, and new allies, to prevent an otherworldly cataclysm from consuming her and all of Arkham.

Arkham Horror

It is the height of the Roaring Twenties – a fresh enthusiasm for the arts, science, and exploration of the past have opened doors to a wider world, and beyond… And yet, a dark shadow grows in the city of Arkham. Alien entities known as Ancient Ones lurk in the emptiness beyond space and time, writhing at the thresholds between worlds. Eldritch rituals must be stopped and alien creatures destroyed; before the Ancient Ones make our world their ruined dominion. Only a handful of investigators stand against the horrors threatening to tear this world apart. Will they prevail?
