Screen destroyed - that where the smoke is coming from in church (6)
I believe the answer is:
censer
'screen destroyed that where the smoke is coming from in church' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I don't see?
