The brutal murder of two partners of a financial advice company in Barcelona unleashes a huge police operation that implicates Germán Rojo, a powerful figure who believes himself to be untouchable, conferred with the gift of immunity and far above other mortals, mere repulsive cockroaches to be crunched underfoot whenever he pleases. But he has a weak point. Melba, a young woman determined to show him that even cockroaches will fight to the death when it's a matter of survival or revenge. Corruption, scandal, money laundering, espionage, violence, sex… are some of the ingredients of this novel in which Andreu Martín offers an extraordinary critique of our present times. An up-to-the-minute work, with lively, incisive dialogue.
