Nadia Bishop

Nadia Bishop is the mother of Heist Society protagonist Kat Bishop who died long before the start of the series.

Physical Appearance
Kat is said to resemble her mother very strongly. Therefore, we can assume that Nadia, like her daughter, was a petite woman, with dark hair, bright blue eyes, and a heart shaped face. Nadia is also said to have resembled her sister, Irina.

In Heist Society, Kat has a nightmare about her mother where Nadia wears a red coat.

Life
Little is known about Nadia, who died approximately nine years before the series begins. She was, during her life, a very well respected thief, who was taught by Uncle Eddie. She was admired even by men such as Arturo Taccone. Kat is said to have inherited her skills as a greaseman from her mother.

At some point in her life, Nadia came into possession of one of three Eggs of the Magi, the Frankincense Egg, which Kat received after her death.

At another point, presumably as a teenager or young adult, Nadia met Bobby Bishop, and brought him home to Uncle Eddie's brownstone. She then trained him in the art of the long con, and also presumably, fell in love with and married him.

On at least one occasion, Nadia worked with Abiram Stein, believing that her skills as a thief would help Mr. Stein recover lost works of art, and return works of art to their rightful owners even when impeded by bureaucracy. The one thing Nadia could not steal, according to Mr. Stein, was her ancestor's portrait, Girl Praying to Saint Nicholas, which was eventually returned to Kat by Visily Romani.

Kat has very few memories of her mother, but associates her with the smell of baking bread, the sound of pigeons scattering on the sidewalk, and old Russian folk songs.

On her blog, Ally Carter once revealed on her blog that Nadia did not die under mysterious circumstances, but did not give any more information about what happened to her.
