King's Mother

The King's Mother is the mother of Jerome Beckett and is the grandmother of Mortimer Beckett. She appears in Mortimer Beckett and the Lost King in the final chapter, Rhinia Castle. She is seen in the West Wing where she recognizes Mortimer, but can't remember. Giving her the display case will help her regain her memory. She gives Mortimer a cloak of invisibility and calls him "grandson" much to Mortimer's confusion.

Looks
Jerome's mother has short gray hair with a red dress. She also wears a big necklace, earrings, and a tiara.

Trivia

 * She is also either the mother of Mortimer's mother or father.
 * She is the only known girl relative of Mortimer.
 * Since Mortimer was confused at why she called him "grandson", this could imply that Mortimer has forgotten all about her in the past years and never met her before due to her living at a castle.
