She created several successful TV series in the 1980s and 1990s, all of which featured women in the leading roles.
These included the World War II female internee drama Tenko (1981-5) for the BBC, secret agent drama Wish Me Luck (1988–90) for London Weekend Television (LWT) and the taxi-firm series Rides (1992-3), again for the BBC.
After this she worked in the BBC Features, Current Affairs and Drama departments as a freelance producer and director.
After the launch of Channel 4 in 1982, she set up her own independent production company, Warner Sisters, which initially focussed on making television programmes.
In 1983 she published "Women Beyond the Wire: A Story of Prisoners of the Japanese 1942-45" which she had co-written.
