Communication from Alison I destroyed (7)
I believe the answer is:
liaison
'communication' is the definition.
(liaison is a kind of communication)
'alison i destroyed' is the wordplay.
'destroyed' is an anagram indicator.
'alison'+'i'='alisoni'
'alisoni' anagrammed gives 'LIAISON'.
'from' is the link.
(Other definitions for liaison that I've seen before include "Communication between groups or units" , "Binding agent of a sauce; secret relationship" , "carryon" , "Mutual communication and co-operation" , "A contact or affair" .)
