"Surely you don't mean me!?" (3)
I believe the answer is:
moi
'surely you don't mean me?' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for moi that I've seen before include "You surely don't mean me?" , "Just me, monsieur" , "egoist" , "it's the writer being facetious" , "Me - in France" .)
