Psychological horror meets police procedural in this chilling tale about a rare quirk of the funeral industry.

When Abby Carlson's job as a dietitian comes to mind now, it's accompanied by a looming threat: the Minneapolis serial killer who's been targeting women based on the first letter of their jobs, and who's ripe to pick a "D" victim. He follows his gruesome routine—preserving and posing the corpses per their professions, then posting his exploits on social media. But the threat is abstract in a city as big as Minneapolis...until Abby finds herself drugged in the back of a van, the latest potential viral hit.

In response to the kidnapping, Detective Cal Randall is called back early from mandated medical leave. Working with the FBI, he's been on the trail of the "Profession Killer" since the start. Despite what's become crippling anxiety he still has to work to control, there's no choice about where he needs to be. A demented killer must be stopped, and Abby—the last of PK's remaining letters—must be saved.
