Fool around court in trouble with detective inspector (3,4)
I believe the answer is:
act dido
'fool' is the definition.
(I've seen this before)
'court in trouble with detective inspector' is the wordplay.
'court' becomes 'ct' (abbreviation used in road names).
'in' means one lot of letters goes inside another.
'trouble' becomes 'ado' (both can mean bother or commotion).
'with' means one lot of letters goes inside another.
'detective inspector' becomes 'DI'.
'ct' inserted into 'ado' is 'actdo'.
'actdo' going around 'di' is 'ACT DIDO'.
'around' is the link.
(Another definition for act dido that I've seen is " fool".)
