Amy Boxer, the precocious daughter of London kidnap consultant Charles Boxer and Detective Inspector Mercy Danquah, has drifted from melancholy and frustration to drastic action: she's leaving home. But Amy can't just walk out, and goads the talents of her parents, with a challenge: YOU WILL NEVER FIND ME.
Amy's destination: Madrid. Here, in the strobe-lights of bars and crowded dance clubs, she's anonymous and untraceable. Except to a volatile, unpredictable leader in the Madrid drug trade, the man known only as El Osito.
Charles Boxer will use his very specific set of skills to retrace Amy's quickly vanishing steps, while DI Danquah takes on her own case in London: a young boy, Sasha Bobkov, has gone missing. Is the disappearance connected to Sasha's father, a retired agent of the Russian secret service, who is working to discover who poisoned his former fellow agent, Alexander Tereshchenko.
As Danquah begins her search for Sasha, a body is found in Madrid. Amy's father may be the next target.
