Monique Bond is the mother of James Bond and the spouse of Andrew Bond. Like her husband, the character has only a brief mention in Fleming's penultimate novel, You Only Live Twice. Although alluded to in 1995's GoldenEye and 2012's Skyfall, she has never been portrayed in film.
It was not until the penultimate novel, You Only Live Twice, that Ian Fleming gave Bond a sense of family background, using a fictional obituary, purportedly from The Times. The book was the first to be written after the release of Dr. No in cinemas and Sean Connery's depiction of Bond affected Fleming's interpretation of the character, to give Bond both a sense of humour and Scottish antecedents that were not present in the previous stories. The novel reveals Bond is the son of a Scottish father, Andrew Bond, of Glencoe, and a Swiss mother, Monique Delacroix, of the Canton de Vaud. When his parents are killed in a tragic mountain climbing accident in the Aiguilles Rouges near Chamonix, eleven-year-old James is orphaned.
In Jeffery Deaver's continuity, it is revealed that, while she pretended to be a freelance photojournalist, Monique was really a freelance Spy Hunter for MI6. Monique was assassinated in the Alps by Russian operatives in a Soviet "Steel Cartridge" operation to take out the spy who had come too close to exposing several Russian agents, and took out her husband in the process.
The resulting police investigation resulted in the operation being declared as a tragic accident, they did find a chrome cartridge of bullets in the snowdrift that appeared to kill them. While its presence was never explained, It was left by the Soviet operative as a warning to the SIS.
She resided in Skyfall Lodge before her death alongside Andrew, leaving James distraught. After that, his primary caretaker became Kincade, the gamekeeper of Skyfall Lodge. Andrew and Monique are mentioned in Skyfall. It is shown that James does not like to talk about his roots or his parents.
