Little is known about Isobel prior to her introduction in the book, but it is discovered that she was formerly married and that she pawned her ring to get to London. Marco Alisdair meets Isobel when he finds her reading his notebook.
When Marco first meets Isobel, she is described as being around eighteen years old, give or take. Her eyes are light, and her hair "is an indeterminate color that cannot seem to decide if it is blond or brown" (98)
