Surgeon in the glove trade! (3)
I believe the answer is:
vet
'surgeon' is the definition.
(I've seen this in other clues)
'in the glove trade' is the wordplay.
'in' says the answer is hidden in the clue.
'VET' can be found hidden inside 'the glove trade'.
(Other definitions for vet that I've seen before include "animal doctor to > investigate" , "'Examine this doctor, in short (3)'" , "Check someone for suitability" , "Animal doctor, in brief" , "Old soldier (inf.)" .)
