Trick one into performing unpleasant task in large city (8)
I believe the answer is:
shanghai
'trick' is the definition.
(I've seen this before)
'one into performing unpleasant task in large city' is the wordplay.
I cannot quite understand how this works, but
'one' could be 'an' (an apple is one apple) and 'an' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for shanghai that I've seen before include "Force into service" , "'What shall we do with a drunken sailor?'" , "Drug and put on a ship" , "Dragoon" , "Kidnap in Chinese seaport?" .)
