Father leave lawman in temple? (6)
I believe the answer is:
pagoda
'temple?' is the definition.
(pagoda is a kind of temple)
'father leave lawman' is the wordplay.
'father' becomes 'pa' (pa can mean dad or father).
'leave' becomes 'go'.
'lawman' becomes 'da'.
'pa'+'go'+'da'='PAGODA'
'in' acts as a link.
(Other definitions for pagoda that I've seen before include "Hindu temple shaped like pyramid" , "Eastern temple, usually a tower" , "Eastern building" , "Hindu or Buddhist temple" , "Asian temple with upward curving roof" .)
