Vicious gaoler is in women’s wing (8)
I believe the answer is:
seraglio
'women's wing' is the definition.
(women's quarters in an Ottoman palace)
'vicious gaoler is' is the wordplay.
'vicious' indicates anagramming the letters.
'gaoler'+'is'='gaoleris'
'gaoleris' with letters rearranged gives 'SERAGLIO'.
'in' is the link.
(Other definitions for seraglio that I've seen before include "Harem - eg sailor (anag)" , "Group of women" , "Gaolers I found in Turkish women's quarters" , "Muslim wives" , "I've made a mistake!" .)
