A literary detective story ingeniously told in ten cases. John Dorn is a classic gumshoe. His woman has left him, he lives in his office, and he drinks too much. His one friend, a lawyer named Demetri, hands Dorn an infinite supply of hopeless cases and lost causes, to which Dorn, ever the champion of the underdog and the oppressed, is drawn to “as a sledgehammer is to a kneecap.” A superlative work of hardboiled literary detective fiction, The Midnight Promise wonderfully evokes the underbelly of contemporary Melbourne, its battlers, its hard men, its victims, and its ill-fated heroes.

The story of detective John Dorn told in ten cases. The "cases" are as different as can be, but each one reveals a little more of Dorn's own troubled past and his dire present, leading to a final confrontation with his arch nemesis: himself.
