Adair also created Compact, the first British TV series to feature a regular black character.

Born in Darjeeling, India, Adair worked as an ambulance driver during World War Two and wrote the novel Blitz on Balaclava Street about her time behind the wheel, under the pen name Clare Nicol. She also acted briefly and appeared in the film My Brother Jonathan in 1948 and on BBC TV drama Lady Precious Stream two years later.

She also co-wrote BBC children's programmes like At Your Service, Ltd and Stranger from Space in the early 1950s.
