In the field, just the fellow for Thora Hird? (5,3)
I believe the answer is:
third man
'in the field just' is the definition.
I can't tell whether this defines the answer.
'fellow for thora hird?' is the wordplay.
'fellow' becomes 'man' (fellow can mean a man).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'thora' becomes 't' (this might be a standard abbreviation I've not previously seen).
't'+'hird'='third'
'man' after 'third' is 'THIRD MAN'.
'the' is the link.
Can you help me to learn more?
(Other definitions for third man that I've seen before include "Cricket fielder - "The ___" (Orson Welles film)" , "Harry Lime" , "position in the field?" , "Cricket fielding position (for a spy?)" , "mysterious one in movie" .)
