An unknown assailant in Galicia murders women who rush to work early every morning. They're inconspicuous. Invisible. Suddenly, literally erased from our world. Meanwhile, in Madrid, a very dangerous assassin is attacking selected billionaires and leaving a short but telling message on the walls of their residences: DEATH TO THE DEVILS. The two seemingly different worlds of two different killers have one thing in common - an unprecedented and explosive confrontation between the social classes of modern Europe. Investigator Lucia is playing the high game. But who plays the victim and who plays the hunter? Isn't the Commissioner just a toy in the hands of ruthless killers after all?

Bernard Minier grew up in the south-west of France and spent his childhood in the Pyrenees. He studied at the University of Toulouse, where Martin Servaz, the protagonist of several of his thrillers, comes from. He has lived near Paris for more than twenty years, is married and has two children. Before Minier surprised French readers and critics in 2011 with his detective novel Frost, he worked as a customs officer. This belated, and perhaps therefore mature, debut won several awards, such as the Elle magazine Readers' Choice Award (in the mystery category) and, most notably, the Prix Polar, a major award given at the Cognac Festival of Detective Fiction. Frost has been translated into several world languages, including English, and was also the basis for the French television series Glacé. Minier's other books are also a success among readers and critics. These are published in the Czech Republic in a brilliant translation by Jiří Žák.
