Yes Tor reconstructed for secretive person (6)
I believe the answer is:
oyster
'secretive person' is the definition.
(I've seen this before)
'yes tor reconstructed' is the wordplay.
'reconstructed' is an anagram indicator.
'yes'+'tor'='yestor'
'yestor' is an anagram of 'OYSTER'.
'for' is the link.
(Other definitions for oyster that I've seen before include "World as place of opportunity" , "Maybe grey" , "Bivalve native" , "Shade of greyish white" , "Native -- seafood" .)
