Perfect for you if...

  • You love historical mysteries set in real times and places, especially when they're grounded in actual events like Eliot Ness's career.
  • You're drawn to slow-burn chemistry between characters who share a traumatic past and unfinished business.
  • You appreciate supernatural elements woven quietly into otherwise grounded crime narratives, not as magic systems but as hints of something stranger.

Maybe not for you if...

  • You want fast-paced procedural crime novels where detectives follow clues methodically. This is atmospheric and character-driven instead.
  • You prefer clear explanations for everything, including Dani's abilities. Harmon leaves some mysteries deliberately unresolved.
  • You're looking for lighthearted historical fiction. The Depression-era setting and serial killer backdrop are genuinely dark.

About this book

In Chicago in 1923, ten-year-old Dani Flanagan comes home to find her parents dead and police at the house. Young patrolman Michael Malone investigates and suspects there is more to the case than authorities want to acknowledge. He is ordered to remain silent, and Dani is sent to live with her aunts in Cleveland. Fifteen years later, Malone is called to Cleveland to investigate a series of murders baffling local law enforcement, including his friend Eliot Ness, the city's director of safety. Malone and Dani encounter each other again in a city gripped by a serial killer. Malone becomes drawn to Dani, who has an affinity for the dead and compassion for the destitute. He recognizes that she may be able to help him solve the case. As violence escalates and Malone and Dani confront the dark secrets connecting them, they race to identify the killer before becoming his next victims.
