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.
