Fixer like you and me reveals flying horse (7)
I believe the answer is:
pegasus
'flying horse' is the definition.
(synonyms)
'fixer like you and me' is the wordplay.
'fixer' becomes 'peg' (I can't justify this - if you can you should believe this answer much more).
'like' becomes 'as'.
'you and me' becomes 'us' (the two of us).
'peg'+'as'+'us'='PEGASUS'
'reveals' is the link.
Can you help me to learn more?
(Other definitions for pegasus that I've seen before include "Flying horse of myth" , "high horse" , "group of stars" , "Exceptional horse" , "madeup creature" .)
