In the charming town of St Andrews, a killer is counting down.
Detective Inspector Clare Mackay, newly relocated from Glasgow, faces her most chilling case yet when a guest at a wedding celebration becomes the first victim in a hit-and-run, a “5” card ominously left on his chest. The next night, another victim falls, with a “4” card marking the scene.
As the murders continue, Clare and her team race against time to uncover the connection between the victims before the countdown ends in more bloodshed. But with secrets lurking in the victims’ lives—and her own past—Clare’s resolve will be tested.
Can she unravel the killer’s twisted pattern before the body count reaches zero?
