DCI Serena Flanagan is asked to sign off the suicide of a severely disabled businessman. It should be an open and shut case.

But something doesn't feel right, and soon the grieving widow's relationship with a local vicar sounds an alarm. With no evidence to back her up, however, have Serena's instincts led her down the wrong path?

Under pressure at home and ignoring orders from her superiors, she must discover the truth. It's an investigation that may cost Serena her job - and her family.
