Julian has suffered three severe blows: His wife has walked out, his mother has died, and Alba, the six-year old daughter he adores, is displaying signs of emotional withdrawal and other problems. While clearing out his mother's apartment he finds an old pistol. It has obviously belonged to his father who had died years before. The gun intrigues him, and although he knows that not having a license he should hand it over to the police, he hesitates, and instead puts it in a safe-deposit box at his bank together with various other items.The next morning, he receives an anxious phone call from an assistant manager who admits that he forgot to lock the deposit box after Julian left. He hurries back to the bank to find that all the contents are there - except for the gun. Shortly afterwards, the popular sports teacher at his daughter's school is shot dead, murdered with the same gun Julian had had in his possession just one day earlier. Could the culprit be his increasingly troubled daughter? Julian must turn to Detective Richard Cupido in this scintillating new thriller by prize-winning author Eugenio Fuentes.
