Misses Damien’s manoeuvres (7)
I believe the answer is:
maidens
'misses' is the definition.
(maiden is a kind of miss)
'damien's manoeuvres' is the wordplay.
'manoeuvres' is an anagram indicator (letters manoeuvred in a new way).
'damiens' is an anagram of 'MAIDENS'.
(Other definitions for maidens that I've seen before include "Misses" , "Females" , "bowlers like?" , "Unmarried girls" , "More than one girl" .)
