Unai López de Ayala (Kraken)

Unai López de Ayala, widely known by his nickname 'Kraken', is an expert criminal profiler for the Vitoria police and the central figure of the White City Trilogy. He is an obsessive and brilliant investigator, haunted by personal tragedies and a past that constantly bleeds into his current cases. His nickname comes from his tenacity and the way he 'wraps his tentacles' around a case until it is solved.

Kraken is a deeply intuitive man who understands the darkest impulses of the human mind, often at the risk of his own mental health. His relationship with his elderly grandfather, who provides him with wisdom and a link to their Basque heritage, adds a layer of emotional grounding to his often chaotic professional life. Through Kraken, Sáenz de Urturi explores the burden of psychological intuition and the personal cost of seeking justice.
