Temple sets up a greyhound agency (6)
I believe the answer is:
pagoda
'temple' is the definition.
(pagoda is a kind of temple)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for pagoda that I've seen before include "place for devotees?" , "Buddhist memorial building" , "Many-tiered building" , "Buddhist tower with several stories" , "Oriental temple, often a tower" .)
