The Ignorance of Blood — Robert Wilson

As a sweltering Seville recovers from the shock of a terrorist attack, Inspector Jefe Javier Falcon is struggling to find the bombers. The death of a gangster in a spectacular car crash offers vital evidence implicating the Russian mafia in his investigation, but it pitches Falcon into the heart of a turf war over prostitution and drugs. Now the target of vicious hoods, Falcon finds those closest to him are also coming under intolerable pressure: his best friend, who's spying for the Spanish government, reveals that he is being blackmailed by Islamist extremists, and Falcon's own lover suffers a mother's worst nightmare. He might be able to bring the perpetrators of the bombing to justice, but there will be a devastating price to pay.
