I got a phone call from my agent, who said that I was up for a part in 'Doctor Who' and would I go for an interview. I went along for an interview with the director of 'The Keeper of Traken', John Black, and John Nathan-Turner. Very soon after this I was told I'd got the part of Nyssa, thought it was a little while before they asked me to carry on. I was very pleased to do so, and quickly signed on the dotted line because the regular pay was very appealing.
