It is winter, just before Christmas. On the cliffs above the transit town of Port Hiver stands a decommissioned lighthouse. Inside, Peter Boniface, a psychotherapist, ponders the falling snow, and his imminent retirement. The arrival of an unexpected visitor plucks him out of his reverie and throws him into the most hazardous case of his career. Boniface's visitor is Bones, a former paramilitary, seeking, he says, "to make a good death". The Lighthouse Keeper is an account of this encounter, the outcome of which will determine everything about what remains of the lives of them both. Nothing less than an examination of the conflicting values underpinning Irish culture, The Lighthouse Keeper traces the intersecting worlds of its two protagonists, from Boniface’s consulting room to the wider world.
