John Rebus and the frequent popular music references and thoughts that Ian Rankin weaves into the stories. However, Rebus' reliance on alcohol is evident and he is often seen drinking in the Oxford Bar. Also, in the television series Rebus is portrayed as being a supporter of Hibernian. This is not found in Ian Rankin's books, he having stated outside the books that Rebus is a Raith Rovers supporter.Rebus's Fife accent is softened as well; in the novel "Tooth and Nail", London Metropolitan Police colleagues find it difficult to understand his speech. Alexander Morton played Rebus in a 1999 BBC Radio 4
The Black Book (Rankin novel) while overseeing the dull minutiae of the Operation Moneybags surveillance, Rebus and Siobhan hear welcome news - Brian Holmes has recovered consciousness. While he cannot remember anything about his assailant, he does tell Rebus that the final name in the Black Book refers to Eddie Ringan, the chef of the "Heartbreak Cafe", who told Brian about the poker game. Rebus returns to the "Heartbreak Cafe", and demands to know what happened on the night of the fire. He knows that Eddie was moonlighting at the Central, which is why he never appeared on the list of people who were there.
