Solicitor in bed, drinking whiskey (6)
I believe the answer is:
Here is my best explanation:
'solicitor' is the definition.
'bed drinking whiskey' is the wordplay.
'bed' becomes 'layer' (I've seen this before).
'drinking' indicates putting letters inside.
'whiskey' becomes 'w' (alpha bravo charlie delta ...).
'layer' going around 'w' is 'LAWYER'.
'in' is the link.
(Other definitions for lawyer that I've seen before include "Professional", "Legal practitioner", "Solicotor or barrister", "Legal professional", "One gives legal advice", "Barrister", "Solicitor or barrister", "Legal eagle", "Brief" and "Attorney in the US".)
