Hide debts, making one angry (7)
I believe the answer is:
furious
'one angry' is the definition.
(I've seen this before)
'hide debts' is the wordplay.
'hide' becomes 'fur' (I've seen this before).
'debts' becomes 'IOUs'.
'fur'+'ious'='FURIOUS'
'making' acts as a link.
(Other definitions for furious that I've seen before include "Enraged" , "Raging" , "Seeing red" , "Extremely angry" , "Livid" .)
