In the labyrinthine fog of London's Bow district, a prominent labor organizer is found with his throat slit in a seemingly impenetrable locked room. The impossible circumstances — a brutal murder without a visible point of entry or exit — ignite a city-wide obsession. As the public clamors for answers, retired detective George Grodman finds himself drawn into a battle of wits with his ambitious successor, not just to unmask the killer but to unravel the very mechanics of a crime that defies logic. Zangwill masterfully weaves a tale where the political undercurrents of the era are as palpable as the mystery itself, creating a world that continues to pulse with life even as the investigation unfolds.
