When 33-year-old Isabel Flores Montserrat quits a promising career with the Spanish police to run her mother's holiday rentals agency in rural Mallorca, it seems that her crime-fighting days are far behind. However, in just a few days, the disappearance of a young British girl, violent murder of an elderly neighbour, and discovery of a Colombian drug cartel threaten to tear apart Isabel s idyllic life. Together with local chief Tolo Cabot, an old admirer of her unorthodox methods, Isabel must race against the clock to untangle a sinister web of crime and restore peace to the island once more.
