Act out a search in burial place (8)
I believe the answer is:
catacomb
'burial place' is the definition.
(I've seen this before)
'act out a search' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'search' becomes 'comb' (combing is a kind of searching).
'act' is an anagram of 'cat'.
'cat'+'a'+'comb'='CATACOMB'
'in' is the link.
(Other definitions for catacomb that I've seen before include "cellar" , "Burial chamber with vaulted tunnels" , "Underground network" , "Underground Roman burial place" , "Burial-place" .)
