Sophie was born on the 20th August 1962 in Greenwich, England and brought up in Blackheath, South East London. After leaving school she took a degree in drama at Manchester University. By singing in working men's clubs she gained her equity card and began her acting career in the theatre.

   

Sophie was appearing in 'Fiddler on the Roof' with Topol when she heard from her agent that she had an audition for a part in Doctor Who. Initially she believed her role would be playing Ray in 'Delta and the Bannermen'. She eventually found out that she'd landed the role of Ace in 'Dragonfire'. Later still she discovered that Ace would be the new travelling companion of the Doctor, then played by Sylvester McCoy

   

Two further seasons followed before the show was finally cancelled. Sophie has had much television work since and has continued to demonstrate her acting and singing talents in the theatre. She married Vince Henderson on July 12 1997 and now has a son named Adam John Henderson, born on the 10th February 2000. Sophie maintains her connections with Doctor Who by attending many fan conventions and by starring in spin-off projects on video and audio.
