A thrilling tale of murder and mystery in a city where history has run a little differently — from the bestselling author of Golden Hill.

In a city that never was, in an America that never was, on a snowy night at the end of winter, two detectives find a body on the roof of a skyscraper.

It’s 1922, and Americans are drinking in speakeasies, dancing to jazz, stepping quickly to the tempo of modern times. Beside the Mississippi, the ancient city of Cahokia lives on – a teeming industrial metropolis, containing every race and creed. Among them, peace holds. Just about. But that body on the roof is about to spark off a week that will spill the city’s secrets, and bring it, against a soundtrack of wailing clarinets and gunfire, either to destruction or rebirth.

The multiple-award-winning Francis Spufford returns, with a lovingly created, richly pleasure-giving, epically scaled tale set in the golden age of wicked entertainments.
