Walpurgis Night, May’s Eve, is always a nightmare in witch-haunted Arkham. There are bad doings, and a child or two frequently goes missing. This year, Miskatonic University students engaged in occult studies have been turning up dead. Arkham Police, in deference to your unusual expertise, have asked for your help to get to the root of the matter. Time is of the essence because after Walpurgis Night, the trail will grow cold and the culprits will retreat to the shadows until the next Witches' Sabbat, when the next cycle of deaths will begin.

As private investigator Howard Lovecraft, you will investigate events based on the stories "The Dreams in the Witch House" (1933), "The Thing on the Doorstep" (1933), and "The Unnamable" (1923).

Arkham Noir is a solitaire card game inspired by the interconnected stories of H. P. Lovecraft and other authors, re-imagined as noir detective stories. Each case stands alone.
