第 9 集: 福爾摩斯推斷出兇手的身份,而威廉則密切觀察他的方法。

Holmes convinces Lestrade to let him escape, promising Lestrade the credit when he solves Drebber's murder. Holmes reveals to Watson the evidence he stole, a wedding ring engraved with the name Lucy. To tempt the mastermind, Holmes places a newspaper advert seeking the ring's owner. In response, William sends Fred disguised as an old woman. Fred claims the ring then escapes before Holmes can catch him. Holmes reveals to Watson inside a hansom cab he solved Drebber's murder. Drebber was suspected of raping lower class women then bribing them. One woman, Lucy, refused and was murdered; meaning Drebber's murderer was Lucy's husband, a large man named Jefferson Hope, the driver of the hansom cab. Holmes explains he has a network of homeless children, the Baker Street Irregulars, who located Jefferson based on Holmes description of his large body. Jefferson reveals his illness will kill him soon anyway and offers Holmes a deal: if Holmes shoots him, a nearby Fred will reveal their master's identity. However, Holmes refuses, preferring to deduce his identity on his own and turns Jefferson in to Lestrade. Meanwhile, as he didn't shoot Jefferson, William deems Holmes worthy to be his nemesis.
