In 1910, Effie James is living a dream for two. Her younger sister is harboring a secret that has left timid Effie determined to fulfill her daring sister's grand plan of seeking out adventure in their small Iowa town. When a British gentleman arrives, disrupting their peace with efforts to find the wife many claim lived her final days at the now abandoned house at 322 Predicament Avenue, Effie is thrust into intrigue she couldn't have prepared for. But what she finds inside will forever link her to the scandal staining the house's walls and to a woman whose secrets promise a curse.

A century later, Norah Richman is living out her late-twin's dream of running their great aunt's bed-and-breakfast on Predicament Avenue--a place Norah believes nothing good can come out of after her sister's abduction and murder thirteen years ago. Her first guest is a crime historian and podcaster, and Norah resolves to stay far away from the charming and enigmatic man--until another guest is found dead. As they dig deeper, something sinister unfurls that will reveal an ominous unknown far greater than the possibility of death itself.
