Detective with hound following male nobody (3,4,3,5)

'nobody' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'detective with hound following male' is the wordplay.
I cannot quite see how this works, but
'detective' could be 'dick' (informal term for a detective) and 'dick' is present in the answer.
'with' could be 'and' and 'and' is present in the answer.
'hound' could be 'harry' (both can mean to harass) and 'harry' is found in the answer.
'male' could be 'tom' (tom can mean a male cat) and 'tom' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
