The woman behind the wheel, the owner of a one-year-old Dalmatian, is driving along the highway and is very nervous: there are traffic jams, and she can’t be late today. Miraculously reaching the place on time, she gets out of the car and right on the street, cold-bloodedly shoots a man and his dachshund. A woman does this not in the heat of irritation, but because it is her job. She is a professional assassin. This is the first in a series of increasingly bloodthirsty crimes, committed in broad daylight and completely inexplicable. The killer isn't even really hiding, but the Parisian police are still at a dead end. It never occurs to anyone to suspect the venerable widow, a former heroine of the French Resistance, and meanwhile she continues her work, plunging deeper and deeper into a very lonely madness, plunging into horror not only her victims, but also her customers, and time after time coming out unscathed ...The French writer and screenwriter, brilliant stylist and subtle psychologist Pierre Lemaitre, a favorite of readers and critics, awarded the Goncourt Prize and other prestigious awards for the novel “Goodbye Up There,” says goodbye to the noir genre, publishing his very first, but only now seen light novel - an eerie and fascinating story of cruelty, aging, loneliness and madness.
