Case of robbery in solicitor’s practice (3-3)

I believe the answer is:

try-out

'practice' is the definition.
(thesaurus)

'case of robbery in solicitor's' is the wordplay.
'case of' says to hollow out the word (remove centre letters) (outsides of).
'in' is an insertion indicator.
'solicitor' becomes 'tout' (someone who solicits business).
'robbery' with its middle taken out is 'ry'.
'ry' placed inside 'tout' is 'TRY-OUT'.

(Another definition for try-out that I've seen is " Test performance".)

I've seen this clue in The Times.
