Gangster gets money as early as this (7)
I believe the answer is:
already
'as early as this' is the definition.
(already can be before now or as early as this)
'gangster gets money' is the wordplay.
'gangster' becomes 'al' (Al Capone).
'gets' says to put letters next to each other.
'money' becomes 'ready' (ready can informally mean cash).
'al'+'ready'='ALREADY'
(Other definitions for already that I've seen before include "Previously" , "thus far" , "As early as this, so soon?" , "Indication of impatience (US)" , "Even this soon" .)
