Perfume dispatched, they say (5)
I believe the answer is:
scent
'perfume' is the definition.
(I know that perfume can be written as scent)
'dispatched they say' is the wordplay.
'dispatched' becomes 'sent' (I've seen this before).
'they say' shows a homophone (sound like).
'sent' is a homophone of 'SCENT'.
(Other definitions for scent that I've seen before include "Get wind of" , "Number of clues" , "Trail" , "Pleasant smell" , "Distinctive odour" .)
