Hands separately interrupting might make someone suspicious (7)
I believe the answer is:
prowler
'hands separately' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'interrupting might make someone suspicious' is the wordplay.
I cannot really understand how this works, but
'someone' could be 'pro' (pro is a kind of someone) and 'pro' is found within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for prowler that I've seen before include "Stealthy walker" , "One moving stealthily" , "Unwanted vagrant" , "One loitering nefariously" , "One sneaks about" .)
