Sin city (5)

I believe the answer is:

sodom

'sin city' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for sodom that I've seen before include "Corrupt biblical city" , "Wicked town of ancient Palestine, twinned with Gomorrah" , "With Gomorrah, it was destroyed for wickedness" , "City fired" , "Bad city" .)

I've seen this clue in the Evening Standard and the King Feature Syndicate.
