The illegal use and trafficking of narcotic substances and their analogs harms health. Their illegal distribution is forbidden and punished by law. Peter James, the well-known crime writer and author of New York Times bestselling books, created a popular detective series about Roy Grace—one of Queen Camilla’s favorite characters. In 2021, the ITV TV series «Grace», based on his books, premiered with plans for six seasons. The story begins on an ordinary Sunday when the Paternosters—husband and wife—set off on a trip. On the way back, they decide to stop at a supermarket. While Nyle is parking, Eden goes into the store for a single purchase—but doesn’t return. She doesn’t appear home, and no one among her loved ones or friends knows where she is. No one has seen her in the supermarket, and surveillance cameras never caught her. Eden vanishes without a trace, as if she dissolved. Nyle is arrested on suspicion of murder, though he vehemently denies it. The police believe he is lying. As the case begins, Superintendent Roy Grace quickly realizes something is terribly wrong.
