At a medieval fair, a killer targets the noble family. At Sir Gerald's medieval festival, the castle is authentic, the jousting is rousing, and the wenches are the sauciest in the land. The only thing missing is decent food. And so Sir Gerald calls in London's gourmet detective, an expert food finder, whose specialties include locating rare ingredients, designing historically accurate menus, and solving the occasional murder. And all three skills will be tested if he is to escape the age of chivalry alive. After the day's first joust, the winning knight falls to the ground, poisoned. Someone is trying to exterminate the gentry of this ersatz fiefdom, and it will take a sure palate and a strong stomach to find out who. To save his own head, the detective must contend with flooding dungeons, stray arrows, and a cast of dwarf knights -- all while struggling to design a menu fit for a king.
