Examiner at home crept so uneasily (9)
I believe the answer is:
inspector
'examiner' is the definition.
(synonyms)
'home crept so uneasily' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'uneasily' is an anagram indicator.
'crept'+'so'='creptso'
'creptso' is an anagram of 'spector'.
'in'+'spector'='INSPECTOR'
'at' acts as a link.
(Other definitions for inspector that I've seen before include "Ticket examiner" , "Examining official" , "senior cop" , "Bus, train official" , "Policeman; compliance official" .)
