Alexandria, year 12 before Jesus Christ. Accompanied by his sons Titus and Khephren, Alix Gracchus, now a Roman senator, arrives in Alexandria, where he is on a mission for his friend and protector, the powerful emperor Augustus. Following the tragic events in The Trahison of Raptors, Alix must find the trace of General Quintus Rufus, whom Augustus suspects to be responsible for the murders of Agrippa and Lepidus. Coming back to Egypt is perhaps also a unique opportunity, for Alix, to finally avenge the death of the father of Khephren, Enak, his former companion of adventures. On the spot, Alix is expected by an old acquaintance, the prefect Barbarus. But also, in the shadow, by other characters, who obviously do not want to him any good... A new narrative arch opens for the famous character created by Jacques Martin: become a senator of Rome as he approaches the age mature, Alix lives in the face of a serious daily event.
