Feud involving archdeacon and one owing money, we hear (8)
I believe the answer is:
vendetta
'feud' is the definition.
(I know that vendetta is a type of feud)
'archdeacon and one owing money we hear' is the wordplay.
I cannot quite see how this works, but
'archdeacon' could be 'ven' (abbreviation for The Venerable) and 'ven' is located in the answer.
'one' could be 'a' (a thing is one thing) and 'a' is found in the answer.
This explanation may well be incorrect...
'involving' is the link.
Can you help me to learn more?
(Other definitions for vendetta that I've seen before include "Lasting feud associated with Sicily and mafia" , "A prolonged feud of Sicilian origin" , "A bitter Italian feud" , "Family blood feud" , "Long-running quarrel" .)
