“Got a gun?”
With those words, David Allen Crockett, a retired police officer who simply wanted to be left alone, finds his seclusion shattered by his friend, therapist Ruby LaCost. At Ruby’s request, Crockett agrees to teach one of her clients, Rachael Moore, how to defend herself with a handgun.
During the course of those lessons, Crockett and Rachael begin an intimate relationship. When Rachael is found dead from an apparent suicide, Crockett is devastated and tries to slink back into his self-imposed seclusion. But things get complicated when Crockett is contacted by Rachael’s aunt, who believes the suicide was staged and claims she has the name of the murderer. Together, Crockett and Ruby begin an investigation that leads them into a world of treachery, deceit, and death.
