The Smile of a Ghost written by Phil Rickman performed by Emma Powell on CD (Unabridged)

The border town of Ludlow has it all: exquisite medieval streets, an imposing ruined castle, a parish church the size of a cathedral and a weight of history and legend. Wealthy people, famous people, have come to Ludlow to live. A sad teenage boy comes here to die ... dramatically, at sunset, in a fall from the ruins.

Accident or suicide? Either way, no great mystery. Or is there? Robbie Walsh was the nephew of former Detective Sergeant Andy Mumford, newly - and reluctantly - retired from West Mercia CID.

When Mumford's ailing mother becomes convinced she's still seeing her dead grandson in the old town, he brings in Merrily Watkins, parish priest, single mum and Deliverance consultant to the Diocese of Hereford.

Is it dementia, delusion or something even more disturbing? Both scepticism and the dark underside of belief threaten Phil Rickman's engagingly open-minded heroine in this brilliantly structured, atmospheric thriller.
