UnSpeakable

From the publisher's website: UnSpeakable: An InSpectres micro-supplement of Lovecraftian horror, madness and mystery. From the introduction to the product: The basic play structure is that of InSpectres, except flavored with a 1920’s setting. Rather than agents working out of a company, the characters are people who have been called together to investigate the Unknown. Naturally, there are changes to the basic rules of InSpectres.
