Arthur Underwood (husband)
|Behind the scenes|
Martha Underwood was Arthur Underwood's wife, who was always very kind to Nathaniel, and was someone he confided his true name to. A rotund woman with gray hair, she was eaten by Jabor in the first book.
Jonathan Stroud has said that she may be a magician who gave up their training to marry Underwood, or she is from a commoner family which associates with the magicians, such as the Hyrneks. She demonstrates knowledge above that of a commoner, for instance knowing what an afrit is and what the capital of Azerbaijan is. Her husband's dislike of commoners would also make it unlikely that she was one.
