Muscle man who kidnaps people (8)
I believe the answer is:
abductor
'muscle' is the definition.
(abductor is a kind of muscle)
'man who kidnaps people' is the wordplay.
I cannot really see how this works, but
'man' could be 'ab' and 'ab' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for abductor that I've seen before include "Paris, for example" , "Taker (of someone)" , "Muscle" , "One removing by force" , "Person snatching, eg, a child" .)
