Lives in a row of shops — bliss! (8)
I believe the answer is:
paradise
'bliss' is the definition.
(I've seen this in another clue)
'lives in a row of shops' is the wordplay.
'lives' becomes 'is' ('be' can be a synonym of 'live').
'in' means one lot of letters goes inside another.
'a row of shops' becomes 'parade' (I've seen this before).
'is' going within 'parade' is 'PARADISE'.
(Other definitions for paradise that I've seen before include "Garden of Eden" , "Elysian fields" , "Sensual garden" , "one enjoyed before the fall" , "Place of utter bliss" .)
