A famous novelist's newest book is apparently based on old cases of U.N.C.L.E. versus Thrush. Thrush sets out to find out how the woman has inside information on them, but she ends up with amnesia and Napoleon takes her back to her home town in the hopes of jarring her memory.

U.N.C.L.E. and Thrush race to acquire a dress. Its pattern forms a code of Thrush's five-year report, and Thrush can't let it fall into U.N.C.L.E.'s hands.
