When a successful businessman is brutally murdered, a long list of suspects develops that is filled with colleagues, ex-lovers, and debt collectors. But no one is more suspicious than his beautiful wife and her young lover. That is, until the victim's business partner suffers the same gruesome fate and another murder, seemingly unconnected except for the killer's signature, occurs soon after.

Confounded, Detective Geraldine Steel is left with only one more lead: DNA at the crime scenes pointing to two women — one dead and one in prison.

With a steady stream of bodies arriving at the morgue, Detective Geraldine Steel and her team are in a race against time to stop a vicious killer.
