She went to Dallas in a best-selling novel, etc. (6)
I believe the answer is:
stella
'she' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for stella that I've seen before include "Swift alias for Esther" , "lady?" , "Swift favourite" , "- Gibbons (Cold Comfort Farm)" , "____ McCartney, fashion designer" .)
