A Dark Mind — T.R. Ragan

A serial killer is terrorizing Sacramento, preying on happily married couples and unleashing unspeakable cruelties upon his victims. The ordeal rekindles disturbing memories for private investigator Lizzy Gardner, who barely escaped a serial killer's clutches only years ago. But while most Sacramento residents are hiding in the shadows, paralyzed by fear, Lizzy is compelled to go after the Lovebird Killer.

So it's no surprise that, when a routine workers' compensation case suddenly leads her and her two young assistants onto the killer's trail, she welcomes the chase, determined to bring him to justice before he can claim another victim. She never imagines he could be two steps ahead, watching her every move and plotting his bloodiest, most triumphant conquest of all.
