Singer ____ Reddy (5)
I believe the answer is:
helen
'singer reddy' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for helen that I've seen before include "Greek woman famed for beauty" , "Immortal beauty of Troy" , "Woman taken to Troy by Paris" , "Was this the face that launch'd a thousand ships?" , "legendary Greek figure" .)
