Godless little devil with evidence of debts (7)
I believe the answer is:
impious
'godless' is the definition.
(similar in meaning)
'little devil with evidence of debts' is the wordplay.
'little devil' becomes 'imp' (I've seen this before).
'with' is a charade indicator (letters next to each other).
'evidence of debts' becomes 'ious' (I've seen this in other clues).
'imp'+'ious'='IMPIOUS'
(Other definitions for impious that I've seen before include "Lacking veneration or respect" , "9 [DEMON]" , "Irreverent; wicked" , "Lacking reverence for God" , "Ungodly" .)
