Ouroboros

Jacot is a silent executioner: he kills, he carries out orders, he never fails at his task. When Perrin, an overly talkative guard, brings him a child to execute, he chooses to defy the royal order and lets the child escape. Jacot must then face the consequences of his act: if he is found out, he will be condemned himself. He will have to cover his tracks and craft a lie so perfect that Perrin will believe it.
