Part of Quinn & Costa
First published 2020
Kara Quinn is out for an early morning jog in Liberty Lake when she finds the body of a young nurse. The death is precise, controlled, and unmistakably personal in its fury. FBI Special Agent Matt Costa recognizes the signature immediately: the Triple Killer, a psychopath who surfaces every three years, takes three lives, and spaces each murder exactly three days apart. That clock is already running. Kara and Matt are not natural partners. She is a sharp-edged local detective; he is a driven federal agent with his own agenda. Working together, they dig into the killer's pattern, trying to crack the logic behind the numbers before the next victim turns up. The case pulls them deeper into the killer's psychology, and the pressure between Kara and Matt shifts from friction to something harder to name. The investigation turns personal when the team realizes the killer may have chosen his next target from inside their own circle. They are no longer just hunting a murderer. They are racing to protect one of their own, with three days left and no margin for error.
