When a pub landlady is stabbed to death and her little finger cut off,
her husband, Roly, is the prime suspect. However, as Nikki, Jack, and
emotionally fragile detective, DI Kate Warren, piece together mounting
evidence, inconsistences lead Nikki to believe Roly's innocent. And
she's desperate to reunite him with his traumatised daughter, Emma,
who faces a life in foster care if her father is imprisoned.
Isolated in her quest to prove Roly's innocence, Nikki is defeated when
Roly is charged with murder, about to lose his daughter forever. But
when Nikki and Leo unearth several old murder cases where the
victims' fingertips were cut off, they begin to suspect Roly is the new
target of a serial killer. And the spotlight soon falls on ex-cop Alan Lane,
who served 8 years for killing his wife, Imogen, despite her body never
being found, only her severed fingertip.
