From publisher blurb:
A strange background hum starts to affect the non-native residents of Taos City, in the New Mexico Territory. A respected professor, intrigued by the seemingly localized aural affliction, sends a telegram to the investigators, asking for their help in uncovering the source. Conflicting stories, a trio of conspirators, and a cultural divide will complicate their investigations in to hum. Will the investigators be able to help the people of Taos and the nearby Pueblo?
The Taos Hum is an adventure for Cthulhu by Gaslight, a Victorian setting for Chaosium's horror roleplaying game, Call of Cthulhu.
Laid out like one of the popular Victoria-era Penny Dreadfuls, the scenario is supported by handouts, maps, NPCs and a new threat for your Call of Cthulhu games.
