Who is Miriam Naumann from Bee Season: A Novel and what is their importance?

Miriam (Grossman) Naumann is Saul Naumann's wife and the mother of Eliza and Aaron. Miriam is an only child whose wealthy parents are both killed by an automobile while they are out for a walk. She is an obsessive-compulsive kleptomaniac and a rabid perfectionist who is unable to form deep attachments to other people. Miriam's most profound relationships are with objects. Miriam's external locus of control is solidified the first time she experiences "Perfectimundo." She views her kleptomania not as stealing, but as a way to bring together the missing parts of herself. Taking things that do not belong to her is Miriam's way of establishing order in the world. Her fragmentation prompts Miriam to steal and then arrange the stolen goods in a storage space, which she calls her kaleidoscope.
