Sebastian has long been haunted by the disappearance of his father, Jack Messenger: celebrated travel writer, potential spy and murder victim, his absent presence and equivocal past continue to cast inescapable shadows over his son, who must also contend with his ageing mother's fragmented memory and his own dereliction of a partner.

So who is the stranger that buttonholes Sebastian at an academic conference on the Welsh coast, and reveals lies and transgressions neither outgrown nor comprehended? How does he know Sebastian, and what are his connections to Jack Messenger?

Equivocator, in a story that stretches from Egypt to Germany, from Iran's Zagros Mountains to the Gower coastline, is a study of fathers and sons, lovers and betrayers, loss and recovery, and combines dark fable, satire and a love story in its pursuit of the question: can Sebastian find his own salvation, despite the inheritance from his father?
