Vitoria, 2019. , una novela ambientada en el medievo, se publica bajo un misterioso seudónimo: Diego Veilaz. Victoria, 1192. Diago Vela retorna a su villa después de dos años en una peligrosa misión encomendada por el rey Sancho VI y se encuentra a su hermano Nagorno desposado con la que era su prometida, la intrigante Onneca de Maestu. Unai Lopez de Ayala, Kraken, se enfrenta a unas desconcertantes muertes que son idénticas a los asesinatos descritos en la novela . Las investigaciones llevaran a Kraken hasta el señor de la torre de Nograro, una casa-torre fortificada habitada desde hace mil años por el primogénito varón. Pero el reverso de tanta nobleza es la tendencia de los señores de la torre a padecer el trastorno de identidad múltiple, un detalle que arrastrará a Estíbaliz a vivir una arriesgada historia de amor. Kraken is enjoying life as a family man, content to spend his days with Alba and their young daughter Deba. But there's no rest for the weary, especially when you're the most famous investigator in Vitoria. Kraken and Esti are charged with investigating the mysterious disappearance of two sisters and finding it hard to make any headway when a wealthy businessman's murder appears to shine a light on the case. The man was poisoned with a medieval aphrodisiac—a crime that has eerie similarities to one detailed in the novel everyone in Vitoria is buzzing about. When the two sisters are discovered trapped behind a wall—bricked up alive—the parallels to the novel are undeniable. With the author's identity a closely held secret, will Kraken be able to track down the killer before they can strike again? Or will Vitoria's sordid underworld finally break Kraken, and his family, apart.
