From publisher blurb:
Orpheum Lofts is a thriller/ horror role-playing scenario inspired by Dario Argento's Three Mothers Trilogy [Suspiria (1977), Inferno (1980) and Mother of Tears (2007)], Polanski's The Tenant (1976) and Rosemary's Baby (1968), '80s and '90s sitcoms, and romantic comedies. Yes, it's a strange mix, but it will get weirder… As usual in Red Room adventures, there is no predetermined plot, only suggested ones, and no described scenes; instead, there are many story seeds. Though it was planned for a series of connected stories set in the mid-80s, Orpheum Lofts can easily be turned into a one-shot. The timeline isn't set in stone either.
This book contains the scenario previously published by Postmortem Studios as part of the Postmortem Giallo series and also part of Her Heart was a Locked Room, and Nobody had the Key: A Giallo Series Companion, adapted to old-school mechanics.
