Guide our group, leading that woman (5)
I believe the answer is:
usher
'guide' is the definition.
(ushering is a kind of guiding)
'our group leading that woman' is the wordplay.
'our group' becomes 'us'.
'leading' is a charade indicator (letters next to each other).
'that woman' becomes 'her' (I've seen this before).
'us'+'her'='USHER'
(Other definitions for usher that I've seen before include "Escort (to a seat)" , "Court or parliamentary official" , "Doorkeeper in court of law" , "Introduce" , "falling house" .)
