“Grey Souls” is not just a thriller. This is a deeply powerful psychological novel, which, as Entertainment Weekly very accurately notes, is more reminiscent of Camus than Simenon. So, France. Small provincial town. The First World War is in full swing. Human life is worth almost nothing, and it seems things can’t get any worse. But, as it turns out, there is no limit to grief, just as there is no limit to villainy. A little girl, Day Beauty, was found murdered. Who dared to commit this terrible murder? The main character of the novel begins an investigation and understands: anyone could become a murderer, because there are no people with bright souls left in the town.
