The first of the twelve "apostles" was brilliantly discovered by Shizuku. It is now time to embark on a second mystery that Tominé intends to solve this time. But before that, the moment has come to validate Shizuku's selection of French wines. In doing so, Miyabi must also break through the shell of his old friend Takasugi, who is both a judge and a party to this selection. Our two heroes thus lay their hands on the centerpiece of their collection, a mysterious 1970 Château Médoc.
