Ratigan's Lair

Ratigan's Lair is the hideout of Basil of Baker Street's archnemisis, "the nefarious Professor Ratigan". It is stationed in a wine cellar, and serves as the home of not just Ratigan, but also Fidget (before his turn to good), Ratigan's thugs and Felicia, Ratigan's enormous pet cat. It was also the place where Hiram Flaversham and Olivia Flaversham were taken after their capture by Fidget; subsequently, this was also the place where Basil and Dr. David Q. Dawson were captured and placed into Ratigan's death machine. After The Great Mouse Detective, Ratigan's lair is presumed abandonded.
