Hoaxer going to church in Worcs town (13)
I believe the answer is:
kidderminster
'worcs town' is the definition.
(town in Worcester)
'hoaxer going to church' is the wordplay.
'hoaxer' becomes 'kidder' (I've seen this before).
'going to' means one lot of letters go next to another.
'church' becomes 'minster' (minster is a kind of church).
'kidder'+'minster'='KIDDERMINSTER'
'in' acts as a link.
(Other definitions for kidderminster that I've seen before include "Carpet-making town of Worcestershire" , "in the Midlands" , "Town renowned for carpets" , "Town on the Stour" , "Carpet town" .)
