Lieutenant Felipe Manley, of the National Intelligence Center, has just discovered that the Meteosat satellite is in danger. Unless measures are taken to prevent it, the Cuencasat satellite will self-destruct in four days, irreparably damaging the European satellite. Ignorant of all of this, Elvira Ballesteros, an unemployed school teacher, has just earned her private investigator's license. With her son Felix, she's about to take on her first case: the disappearance of a saluki. The mother-and-son team has little clue, though, that the routine case may hide the keys to resolving an international crisis. What possible connection could there be between a missing dog and the threat to the Meteosat satellite? This humorous detective story is also a gripping homage to the noir genre and spy novels.
