She also supplied many original scripts and dramatisations to BBC Radio drama, including The Archers. She wrote the screenplay for Cameleon, which won the Golden Spire Award for Best Dramatic Television Feature at the 1998 San Francisco International Film Festival.
Juliet Ace was the third daughter of Charles and Glenys Ace, born and raised in Llanelli, Carmarthenshire in South Wales. She was educated at Llanelli Girls' Grammar School, City of Coventry Training College, which was soon to become Coventry College of Education and be incorporated into the University of Warwick, where she specialised in drama and art, and then trained at Rose Bruford College of Speech and Drama.
She taught for three years in St Mary Cray before joining a children's theatre and then working in The Grand Theatre, Swansea for two seasons, in weekly repertory. In 1964, she began to work with children with special needs.
After her marriage to Richard Alexander in 1966 she moved to Dartmouth, Devon, where her husband worked as a civilian lecturer at the Britannia Royal Naval College. For the next 18 years she brought up their two children: Daniel Alexander (now a business consultant) and Catherine Alexander, a theatre director and drama teacher. Meanwhile Ace continued working with special-needs children, privately and in local schools, and directed and acted with local drama groups.
