Not to be confused with the Series 5 character of the same name.
Maggie was an old woman who lived on the estate. Her cat was run over and Curtis ressurected him, and she gave him a Victoria sponge cake as a thank you. This later led to her cat turning into a zombie and attacking and eating her. When Curtis returned the cake tin, he found the zombified cat eating her unconcious body. Coming back alive (as a zombie) she was curious as to why they were in her flat, and attacked Rudy, but was killed with a hammer by Curtis. As the gang left with the zombie cat, her corpse was left in her flat.
