In this provocative novel Mark Blacklock portrays the true and complex history of John Humble, aka Wearside Jack, the Ripper Hoaxer, a timewaster and criminal, sympathetic and revolting, the man hidden by a wall of words, a fiction-spinner worthy of textual analysis. In this remarkable work, John Humble leads the reader into an allusive, elusive labyrinth of interpretations, simultaneously hoodwinking and revealing. I'm Jack is a riveting novel about truth, lies, prison and shame. It is also a profound and furious love letter to Sunderland. It is a puzzle, a hoax, a multi-voice portrait and a virtuoso assemblage of textual elements. I'm Jack announces the arrival of a radically talented and innovative novelist.
