Melchor, the son of a prostitute, went to prison as a teenager, convicted of working for a Colombian drug cartel. Behind bars, he read a book that changed his life: Les Misérables. Then his mother was murdered. He decided to become a cop.
 
This new case, in Terra Alta, a remote region of rural Catalonia—the murder of a wealthy local man and his wife—will turn Melchor’s life upside down yet again.
