As dark and gripping as ever, this is Donato Carrisi’s latest thriller. A young woman wakes up in a hospital bed, disoriented and with a broken leg. The room she is in has no windows, only a huge mirror lining one wall, although she can’t see her reflection in it. With her is a man who introduces himself as Dr White, a criminal profiler. He explains that her name is Samantha, that she has been kidnapped and kept prisoner, but managed to escape, and that his job is to find her kidnapper. However, the hunt will not take place in the outside world, but in Samantha’s mind. White reveals to Samantha that she is no longer thirteen, but twenty-eight. In other words, she was held prisoner for fifteen years. With his help, she gradually starts to recall certain episodes from her captivity. In a city overcome by a ferocious heatwave, where the people have taken to sleeping during the day, and leaving their homes only at night, a private detective called Bruno, who has spent years investigating Samantha’s disappearance, learns of her liberation. Now, stricken with a heart disease, the detective has only two months to live, but nonetheless, he takes up the hunt once more.
