Córdoba, the city of three cultures, awakens beneath the shadow of a crime that defies all logic. Inocencio, a respected jeweler with deep ties to the Masonic brotherhood, is found dead in a scene exuding a disturbing mysticism: his body, surrounded by arcane symbolism, lies with hands covered in white gloves—a silent testament to a ritual that has only just begun.

Inspector Rafael Infante, whose astuteness is surpassed only by his deep skepticism toward the occult, is drawn into a labyrinth of secrets alongside Sub-inspector Cristina. What initially appeared to be an isolated act of violence soon unveils itself as a methodical hunt aimed at the very heart of the Maimónides Lodge. Amidst shadowy gentlemen’s clubs and the haughty local elite, the investigators must decipher a centuries-old language to stop a criminal hand operating with chilling, surgical precision.

Aided by veterans like Octavio—keepers of truths that history has chosen to forget—Rafael and Cristina delve into a Córdoba of dark alleyways and pasts demanding vengeance. In this deadly game of chess, where every piece is a symbol and every move could be their last, the Masonic Code is the only key to unmasking an executioner who has turned resentment into lethal art.

Will the inspectors manage to halt the killer’s pulse before the gavel strikes its final blow?
