Good and moving death for mafia chief (9)
I believe the answer is:
godfather
'mafia chief' is the definition.
(term for a mafia leader)
'good and moving death for' is the wordplay.
'good' becomes 'g' (abbreviation).
'and' is a charade indicator (letters next to each other).
'moving' indicates an anagram.
'death'+'for'='deathfor'
'deathfor' with letters rearranged gives 'odfather'.
'g'+'odfather'='GODFATHER'
(Other definitions for godfather that I've seen before include "He's a sponsor at Baptism" , "Mafia chief or spiritual parent" , "Religious relation, like Marlon Brando in movie" , "leading exponent" , "Mafia boss" .)
