Enticement in Mumbai titillates (4)
I believe the answer is:
bait
'enticement' is the definition.
(bait is a kind of enticement)
'in mumbai titillates' is the wordplay.
'in' says the answer is hidden in the clue.
'BAIT' can be found hidden inside 'mumbai titillates'.
(Other definitions for bait that I've seen before include "Deliberately annoy or taunt" , "Lure; deliberately taunt" , "Annoy; enticement" , "Set a trap with food" , "Lure; tease" .)
