Succeeded having deployed her mace? I have no idea (6,2)
I believe the answer is:
search me
'i have no idea' is the definition.
(I've seen this in another clue)
'succeeded having deployed her mace?' is the wordplay.
'succeeded' becomes 's' (genealogical abbreviation).
'having' says to put letters next to each other.
'deployed' indicates an anagram.
'her'+'mace'='hermace'
'hermace' is an anagram of 'earchme'.
's'+'earchme'='SEARCH ME'
(Other definitions for search me that I've seen before include "Who knows? 14 [NOT-I] !" , "what a customs officer may do" , "how you'll find what's concealed on my person" , "I certainly don't know" , "I don't know, informally, about cashmere - frisk away" .)
