"a compelling and immersive novel in which every word feels authentic and every chapter draws the reader deeper into the dark and terrifying power of the mind.”—New York Journal of BooksIn 1880s Paris, a doctor encounters a statuette that can drive men mad, secret societies, and a bridge between worlds that threatens disastrous consequences. Throughout, he is assisted and opposed by historical figures such as Charlie Dickens, the son living in his late father’s shadow, a young Sigmund Freud and the ghost of the Marquis de Sade.
