The remaining certainties of Philip's life crumble away when his father's ghost appears in the pub and declares Uncle Alan murdered him. Arming himself with weapons from the school chemistry cupboard, Philip vows to carry out the ghost's relentless demands for revenge. But will Leah, the gorgeous daughter of Uncle Alan's God-fearing business partner, Mr Fairview, prove too much of a distraction? And can the words of a ghost be trusted any more than the lies of the living? Philip makes his decision and when the moment comes to act, he finds himself hurtling towards disaster.
