Place stranger finds tortoise? (7)
I believe the answer is:
plodder
'tortoise?' is the definition.
(thesaurus)
'place stranger' is the wordplay.
'place' becomes 'pl' (I've seen this in other clues).
'stranger' becomes 'odder' (I've seen this before).
'pl'+'odder'='PLODDER'
'finds' is the link.
(Other definitions for plodder that I've seen before include "Slow dull worker" , "One who walks laboriously or works slowly" .)
