It takes a guilty bastard to make a justified bitch.

When a severed finger appears on her doorstep in a seedy Las Vegas neighborhood, Helen Taylor doesn't panic. After all, her life is already a little unconventional. Her house is crammed with decades of accumulated junk, her collection of cats keeps growing, and she regularly carries on conversations with Bobby, her long-dead husband. The unsettling part? Bobby talks back.

But the finger is no figment of Helen's imagination. It points to a brutal murder, and before long, Helen finds herself a prime suspect—and behind bars. Desperate for help, the detective investigating the case summons Helen's sister, Pat, from Phoenix. Pat arrives with two teenage boys in tow, only to discover that her sister's troubles are far more disturbing than she imagined.

When Helen disappears from a mental health facility and another gruesome murder comes to light, the mystery takes an even darker turn. As Pat, the boys, and the detective struggle to separate truth from delusion, they uncover secrets that challenge everything they thought they understood.

In a world where the dead may speak and madness may conceal the truth, solving the murders will require more than ordinary detective work. Some mysteries demand an explanation that defies reason itself.
