When food critic Gabriel Vautrin dies at La Tour d'Argent clutching duck card 1,204,117, Commandant Luc Moreau expects poison, professional resentment, and the usual Parisian appetite for scandal. Instead, the number leads him backward to a pressed duck served in 1968, a dead industrialist, a missing diner, and an old agreement whose beneficiaries have spent half a century confusing discretion with innocence.
As Moreau moves through reservation books, wine ledgers, kitchen memories, family secrets, and the ritual of pressed duck, he discovers that a restaurant serial number became evidence in a financial conspiracy and later a weapon of blackmail. With table nine's surviving guests protecting incompatible versions of the past, Moreau must determine who killed Vautrin before another carefully served course becomes a final one.
