Hustle roughly around detective (6)
I believe the answer is:
sleuth
'detective' is the definition.
(I know that sleuth is a type of detective)
'hustle roughly' is the wordplay.
'roughly' indicates an anagram.
'hustle' is an anagram of 'SLEUTH'.
'around' is the link.
(Other definitions for sleuth that I've seen before include "Detective who follows a trail" , "Sherlock Holmes, for example" , "Track" , "Hustle for a clever detective like Sherlock" , "Follow" .)
