English summary: In 1982, when he was just three years old, Samir was abandoned by his mother on the El Saler beach. She blindfolded him and told him: "don't move, I'll be right back". But she never did. Nobody knew why she didn't come back and that boy ended up in a juvenile center with no identity other than his name and a handful of memories. Samir grew up among orphans and disinherited in the world, but with the determination to have a chance in life. Thirty years after his mother forgot him on that beach, Samir is no longer a helpless child, but a captain of the Judicial Police of Valencia. However, his past will mysteriously come back to look for him. The discovery of the body of a young woman, murdered hours before in the same place where he had been abandoned as a child, will not seem to be a coincidence. The fact that it had her name and her phone number, either. Captain Santos will start an investigation that will become a puzzle where the pieces of his past and that of his mother will end up being essential to discover the truth about that corpse. After all, deep down inside, Samir had always hoped for that: that one day his mother would return to look for him. Narrated with brilliance and emotion, the suspense and the plot become the best claim to read this book. The author builds the story by alternating past and present in a fluid and rhythmic way, knowing that a novel not only requires a good story, but also powerful writing.
