William Blake is a private detective. When he is asked by an eccentric scientist to investigate the whereabouts of his amnesiac missing wife, Louise, Will finds himself entangled in layers of deceptions and disappearances that lead him inexorably back to an unsolved mystery in his own past: the loss of his young daughter Emily.

The case takes Will to brothels, night clubs and amusement arcades in the Scottish seaside resort of Portobello. Identities become confused as his sexual obsession with a night club singer becomes entwined with sightings of Louise, his own torturous memories, and new visions of the lost Emily.

The Existential Detective is a surreal, dreamlike story of loss, incest and what it means to remember.
