Throw sterling to get unscrupulous lawyer (7)
I believe the answer is:
shyster
'unscrupulous lawyer' is the definition.
(I've seen this in another clue)
'throw sterling' is the wordplay.
'throw' becomes 'shy' (shy is a kind of throw).
'sterling' becomes 'ster' (abbreviation).
'shy'+'ster'='SHYSTER'
'to get' is the link.
(Other definitions for shyster that I've seen before include "Unscrupulous or disreputable person" , "Person who acts unprofessionally - sounds bashful" , "Unethical man" , "Unscrupulous practitioner" , "Crooked bar person" .)
