Rich heiress in sports car, did you say? (6)
I believe the answer is:
portia
'rich heiress' is the definition.
(in Shakespeare's The Merchant of Venice)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for portia that I've seen before include "A Shakespearean heroine" , "Advocate of cross-dressing" , "Theatrical "lawyer"" , "Heroine of Shakespeare's ''The Merchant of Venice''" , "Character in "Julius Caesar" or "The Merchant of Venice"" .)
