Author Ivins (5)
I believe the answer is:
molly
'author ivins' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for molly that I've seen before include "Mrs Bloom (Joyce)" , "Diminutive of Mary" , "fish" , "Seller of cockles, mussels" , "Flanders? Yes, she kept saying" .)
