In 44 B.C., the fate of the Roman Republic hangs in the balance. The most powerful man in the world, Julius Caesar, lies dead in the Theatre of Pompey, as politicians and military men ambitiously move to fill the void of power. Marcus Antonius summons the physician Antistius to uncover the truth about the assassination through a Greek technique called "autopsy". But as Antistius discovers more about the crime, the real truth becomes harder to find. Inspired by history's only mention of Antistius in Seutonius's The Twelve Caesars, 23 Knives utilizes contemporary language to weave a darkly comic mystery about politics, patriotism, and the nature of truth.
