In 1991, a serial killer stalked Brooklyn before vanishing. In 2024, he'll pick up where he left off. Being stuck with journalist Jane Ross is the latest in a long list of indignities Miriam Balfour, the first female detective in the 21st Precinct, has to deal with. When Jane uncovers a potential murder in a case written off as an accidental overdose, Miriam finds herself in the middle of her first major case. With time running out before the killer strikes again, Miriam finds herself struggling with Jane's presence. First as a nuisance, but then as something more. Something that could cost her everything. Everyone in Brooklyn knows the Goodnight Man case, and everyone has a theory. Detective Sam Balfour remembers it as the case that destroyed her family. When the killer seemingly resurfaces after thirty years, Sam is forced to do the unthinkable and reach out to the detective who failed to catch him thirty years earlier... her mother, Miriam Balfour.
