I'm a little stuck... Click here to teach me more about this clue!

'a complaint' is the definition.
I know nothing about this answer so I can't judge whether this works.

'goes aside with detectives quickly to make' is the wordplay.
I cannot really see how this works, but
an anagram of 'aside' is 'disea' which is located in the answer.
'make' could be 'do' (do can mean to make or prepare) and 'do' is found within the answer.
This explanation may well be incorrect...
