Solomon Cohen
A character in Dodger, not to be confused with Jack Cohen or Cohen the Barbarian. He is a Jewish watchmaker, and is Dodger's landlord.
Solomon first met Dodger when he was being beaten up by two thugs (they didn't need a reason; this is Victorian England), and the tosher saved him. It seems that Dodger meets a lot of people this way. Dodger was then quite unpredictable; if he had been feeling differently, he would probably have been the one to kick the old man; but as it was, he took him home and the two became firm friends. They soon came to an agreement; Solomon would cook meals, while Dodger would help the man in various small ways. His protection was very helpful, as his hard-earned reputation ensured that even the toughest rogue thought twice before coming near either of them.
Annotation
It is not hard to jump to conclusions when an elderly Jewish man rents spaces to a boy called Dodger in a Dickensian-themed novel. Indeed, the physical description of Solomon matches Fagin (of Oliver Twist) quite well, or at least a Fagin who has stopped committing crime and has completely reformed.
Interestingly, Dickens based Fagin off Isaac 'Ikey' Solomon, a thief who owned a Jeweller's shop. See here for more information.
