Christos Markogiannakis returns with an exciting mystery, darker than ever before. A killer moves invisibly in the center of Athens. His victims: an elderly homeless man, a young Greek-French woman, a Bangladeshi deliveryman. Their only common feature: their eyes have been removed from their bodies.

Detective Christoforos Markou, marked by a personal loss, is called to solve the darkest case of his career. By his side is profiler Roubini Gaetano, struggling to manage a health-damaging new condition, and Detective Konstantinos Manias.

As the circle of blood grows, the protagonists sink into a labyrinth where nothing is as it seems. Faces change roles, victims become perpetrators, and the truth lurks where no one... looks.

What ultimately determines who we are? DNA, environment, or our choices? A gripping novel about the nature of evil, the burden of inheritance, and the relentless need to face – or not to face – the truth.
