Based on the "Detective Touré Saga" books by Basque author John Arretxe. Touré, a Guinean immigrant who has settled in Bilbao and who earns a living as a rough and ready, small-time detective. His skill, intuition and peculiar sense of humour earn him the trust of the Ertzaintza (the Basque autonomous police force) and immerse him in a complex investigation during which he will face myriad dangers: he will gain an intimate knowledge of real-estate corruption, the shady hustle and bustle of the troublesome and multicultural San Francisco neighbourhood, and will even come face to face with the Nigerian mafia.
