Book excerpt: In the tradition of Caleb Carr’s The Alienist and Eric Larsen’s The Devil in the White City comes The Paris Enigma, a gripping tale of murder and the art of crime solving. Written in a strikingly original voice, and poignantly evoking a world about to lose its innocence forever, The Paris Enigma features two detectives who find themselves in a race against time around glorious fin de siècle Paris, encountering all manner of secret societies and solving philosophical puzzles, while also trying to save a dangerously beautiful woman.
