1932. The King of Detectives comes out of retirement, in a desperate quest for world peace!

Across a world barely recovered from the ravages of the First World War, dark forces are stirring. A shadowy cabal of arms dealers and financiers are determined to drag the world into fresh conflict.

Standing against them—Chicago's King of Electricity Billy Clifford, a billionaire determined to rid the world of the scourge of war. Clifford has brought together an elite band of scientists in his Anti-War contest.

But Clifford's scientists are disappearing! Picked off one by one by an international team of hired killers, led by a mysterious female assassin: the Dark Hawk... Princess Vanda... the Devil's Daughter.

But when the Devil's Daughter arrives in Paris to target Count Robert de Langeais, a dedicated scholar and pacifist, and her former lover, she quickly meets her match. The only man who can stop this ruthless killer.

Chantecoq. King of detectives. Master of disguise.

Older, wilier, and aided as always by his irrepressible secretary Meteor, Chantecoq's mission to protect Robert de Langeais and defeat the machinations of the Devil's Daughter will take him far from his beloved Paris. Across the Atlantic on a suspense-filled steamer crossing, and finally... to Chicago.

On the shores of Lake Michigan, France's greatest detective battles to decide the fate of the entire world.

Chantecoq's penultimate adventure, first serialised in Le Petit Parisien in 1932 and never before translated into English, is a truly epic saga of passion and politics, and the stakes have never been higher.
