Dutch town seen in The Dambusters (4)
I believe the answer is:
edam
'dutch town' is the definition.
(I've seen this in another clue)
'in the dambusters' is the wordplay.
'in' says the answer is hidden in the clue.
'EDAM' can be found hidden inside 'the dambusters'.
'seen' acts as a link.
(Other definitions for edam that I've seen before include "Dutch specialty" , "Hard Dutch cheese" , "town in Holland" , "something from the deli" , "edible sphere" .)
