In Hunstanton I organised The Merchant of Venice (7)
I believe the answer is:
antonio
'the merchant of venice' is the definition.
(I've seen this before)
'in hunstanton i organised' is the wordplay.
'in' says the answer is hidden in the clue.
'ANTONIO' can be found hidden inside 'hunstanton i organised'.
(Other definitions for antonio that I've seen before include "-- Vivaldi, composer" , "sea captain in Twelfth Night" , "-- Pappano, conductor" , "merchant threatened by weight loss" , "Italian chap" .)
