Detective Sergeant Michael Brennan of the Wigan Borough Police has no time for tales of ghosts and the afterlife, or of the dead contacting the living. So, when he finds himself investigating the case of a recently widowed young woman, Alice Goodway, who has suddenly developed 'the Gift' of mediumship and has received a threatening letter, he embarks on the inquiry with no small degree of scepticism. But just as Brennan and his colleague, Constable Jaggery, consider how to proceed with the case, something much more sinister takes place – a murder, in Alice's own home.
