Cat Kinsella overcame a troubled childhood to become a Detective Constable. When she's called to the scene of a murder not far from the pub her estranged father runs, she discovers that Alice Lapaine, a young housewife, has been found strangled. Cat and her team immediately suspect Alice's husband, until she receives a mysterious phone call that links the victim to Maryanne Doyle, a teenage girl who went missing in Ireland eighteen years earlier. The call raises uneasy memories for Cat--her family met Maryanne while on holiday, right before she vanished. Though she was only a child, Cat knew her father wasn't telling the truth when he denied knowing anything about Maryanne or her disappearance. Did her father do something to the teenage girl all those years ago? Could he have harmed Alice now?
