Like The Woman in White (5)
I believe the answer is:
ashen
'white' is the definition.
(I've seen this before)
'like the woman' is the wordplay.
'like' becomes 'as'.
'the woman' becomes 'hen' (**).
'as'+'hen'='ASHEN'
'in' acts as a link.
(Other definitions for ashen that I've seen before include "Pale-faced" , "bleached" , "pasty" , "Anaemic-looking" , "Wan - wooden - pallid" .)
