Suddenly, a bat with a crippled wing and peg leg bursts into the Flaversham's workshop, kidnapping Hiram. Olivia searches to find the famed Great Mouse Detective named Basil of Baker Street, but gets lost. A surgeon named Dr. David Q. Dawson, who is returning from a lengthy service of the Mouse Queen's 66th Regiment in Afghanistan, stumbles upon Olivia, and escorts Olivia to Basil's residence. Upon their arrival at his residence, Basil is initially indifferent, but when Olivia mentions the peg-legged bat that kidnapped her father, Basil realizes that Olivia saw Fidget, a henchman of Professor Ratigan, a villain Basil has been trying to arrest for years. It is then revealed that Professor Ratigan kidnapped Hiram to create a clockwork robot which mimics the Queen of the Mice so Ratigan can rule England. Hiram initially refuses to participate in the scheme, but gives in when Ratigan threatens to harm Olivia. Ratigan then announces his plans to kill the Queen and become "supreme ruler of all mousedom" to his henchmen. Meanwhile, as Basil is deducing the case, Fidget appears through the window, scaring Olivia. They give chase as Basil finds Fidget's footprints, declaring that they purse him in order to find Hiram. Basil, along with Dawson and Olivia, takes Toby, Sherlock Holmes's pet Basset Hound, to track Fidget's scent, where they locate him in a toyshop stealing clockwork mechanisms and toy soldiers' uniforms. Fidget then ambushes Olivia from inside a toy cradle and kidnaps her. Basil and Dawson pursue Fidget, but become entangled and fall behind. While searching the shop, Dawson discovers Fidget's checklist, to which Basil does some chemical tests to discover the list came from a riverfront near the Thames. Basil and Dawson disguise themselves as sailors and go into a tavern called the "Rat Trap" and follow Fidget to Ratigan's headquarters. They are caught, and Ratigan has his hooligans tie...
