Following his sensational defection, Philby lived in the Soviet capital until his death in 1988 at the age of 76. His granddaughter gave an interview to British newspaper The Sunday Telegraph, in which she said that her father, John, “never said anything against Kim” and “enjoyed a very good relationship” with him. The family visited Kim Philby in Moscow every year until his death, when Charlotte was five. She told The Telegraph that she remembers these trips, and staying at Kim Philby’s apartment. She said the family would be met at the airport in Moscow “by men in grey suits” who would usher them into a government car and “whiz [them] to the gated apartment block where Kim lived” in downtown Moscow. During those trips, the family would give the double spy supplies of his favorite English foods and magazines. This may surprise some, given that Philby abandoned his second wife, an American, and his five children from his first wife. She had died six years prior to his defection, so the children, including Charlotte Philby’s father, were raised by relatives and family friends.

Charlotte Philby worked as a journalist for The Independent, a London-based British newspaper that ceased print circulation in 2016, and has since been writing as a freelancer. Her first novel, entitled The Most Difficult Thing, features a female protagonist who has to balance her espionage work with her relationship with those closest to her. The author says that Kim Philby’s ghost “hovers over the pages”. She notes that, if her grandfather had any regrets at the end of his life, “they wouldn’t be to do with betraying his country but with the individuals and the family members that he had to dupe and separate from”.
