Rooker Lindström is a reluctant consultant for the Minnesota PD. He can provide a window into evil. His horrifying past gives him the edge. When the body of a woman--missing for eight years--is pulled from the lake, evil comes knocking again. This time with a note meant just for Rooker: Won't you come out and play?
A request from the police. A dare from a killer. And now a plea from a distraught mother whose daughter has suddenly vanished too. If only Rooker could say no. Instead, partnered with Millie Langston, his friend turned private investigator, he's compelled to find a connection between the missing and the dead. It's drawing them into the dark web, conspiracy theories, and an unsolved mystery reaching back thirty years.
The deeper into the investigation Rooker and Millie go, the more exposed they are to a dormant serial killer whose motives--and next moves--are unlike anything Rooker has ever encountered.
