William "Bill" Sikes is a fictional character and the main antagonist in the 1838 novel Oliver Twist by Charles Dickens. Sikes is a malicious criminal in Fagin's gang, and a vicious robber and murderer. Throughout much of the novel Sikes is shadowed by his “bull-terrier” dog Bull's-eye. Role in the novel Dickens describes his first appearance: His girlfriend Nancy reluctantly tolerates, but is intimidated by, his violent behaviour. However, when he thinks Nancy has betrayed him, Sikes viciously murders her. After police identify him as travelling with a dog, Sikes attempts to drown Bull's-eye to rid himself of his companion. In the end he hangs himself while trying to escape. It is left ambiguous whether or not this act was accidental or intentional. Sikes is a somewhat conflicted character. For instance, after preventing Nancy from keeping her midnight appointment with Rose Maylie and Mr Brownlow, he wondered aloud to Fagin if being indoors for so long in their dingy lodging was beginning to affect her after she dedicated the whole day caring for him. After he brutally beats Nancy to death, Sikes apparently is capable of feeling guilt—although the reader cannot be sure the emotion is not merely his suspicion that Fagin lied to him about her betrayal and fear of being arrested for the crime. Sikes lives in Bethnal Green and later moves to the squalid rookery area of London then called Jacob's Island, east of present-day Shad Thames. Otherwise, Sikes's background and early life prior to joining Fagin are not mentioned in the book. Theatrical, cinematic and TV portrayals In the theatre, Sikes was played by Henry Irving opposite Ellen Terry as Nancy in Oliver Twist at the Queen's Theatre in London (1868). Robert Newton first played Sikes on screen in the 1948 British film noir Oliver Twist. Sikes's death is changed slightly: while attempting to swing to another building to escape the mob, he is shot by a police officer and dies while dangling from a building by a rope around his body. Perhaps Newton's portrayal is the closest to how Dickens himself envisioned the character: a vicious, heavy drinking sociopath. Peter Vaughan portrayed Sikes in the BBC's 1962 television adaptation, which saw the character portrayed in a gritty, violent way considered to be faithful to the original book. The scene where he brutally murders Nancy was very controversial at the time, with questions being asked in
