Anthony J Quinn's nine novels have received critical acclaim from the Sunday Times, Guardian, Independent, Financial Times, Daily Mail, Daily Telegraph, Sunday Telegraph, Sunday Express, Sunday Herald, Literary Review, Good Book Guide, Sydney Morning Herald, Books Ireland, Der Spiegel, Irish Times, Irish Independent and other newspapers.

The sole survivor of a murderous ambush, a Belfast police detective is forced into a desperate search for a mysterious informer that takes him to a holy island on Lough Derg, a place shrouded in strange mists and hazy rain, where nothing is as it first appears to be.

A keeper of secrets and a purveyor of lies, the detective finds himself surrounded by enemies disguised as pilgrims, and is drawn deeper into the mysteries of the purgatorial island, where he is forced to confront a series of disturbing secrets and ghosts in his own life.

Haunting and unsettling, Turncoat probes the legacy of the Troubles, the loss of collective memories and the moral consequences for the individual. It is a story of guilt, survival and the terrible price of self-knowledge, told through the voice of a detective with a double life. Descending into paranoia, he uncovers a sinister panorama of cover-ups and conspiracies. The closer he edges to the truth, the deeper he is drawn into the currents of power, violence and guilt engulfing his country...
