One gentle September morning in 1919, the bodies of four sailors are found in the town of Breslau. Next to them is a mysterious note addressed to Inspector Eberhard Mock, in which the killer invites him to play a strange and dangerous game. The stakes in this game are the lives of those around Mok. To find the eccentric killer, Inspector Mock will have to plunge into a labyrinth of secret sects, forbidden pleasures and ghostly shadows. A weakness for alcohol and red-haired women, nightmares and an extraordinary gift for detective - this is Eberhard Mock, one of the most unusual and charming detective heroes. In his dark and mysterious detective story, Marek Krajewski paints a colorful canvas of life at the beginning of the century, in which depraved aristocrats, ruthless criminals, revolutionaries, maniacs and red-haired beauties united in a strange round dance. Reading Kraevsky's detective story, it's as if you're looking into another era - all the historical details are so vividly described, but still the main thing in it is a fascinating detective story that literally takes your breath away.
