Loving a swindle, gang (7)
I believe the answer is:
adoring
'loving' is the definition.
(I've seen this before)
'a swindle gang' is the wordplay.
'swindle' becomes 'do'.
'gang' becomes 'ring' ('ring' can be a synonym of 'gang').
'a'+'do'+'ring'='ADORING'
(Other definitions for adoring that I've seen before include "Loving, worshipping" , "Greatly loving" , "Holding dear" , "Devoted" , "Really getting into" .)
