"Rebecca” writer du Maurier (6)
I believe the answer is:
daphne
'rebecca writer du maurier' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for daphne that I've seen before include "He'd nap around this shiny shrub" , "Shrub - girl's name" , "Shewd, sharp" , "Bay" , "Greek nymph and ornamental shrub" .)
