Policeman crept in so awkwardly (9)
I believe the answer is:
inspector
'policeman' is the definition.
(I know that inspector is a type of policeman)
'crept in so awkwardly' is the wordplay.
'awkwardly' indicates anagramming the letters.
'crept'+'in'+'so'='creptinso'
'creptinso' is an anagram of 'INSPECTOR'.
(Other definitions for inspector that I've seen before include "Person whose job it is to examine efficiency as in schools" , "auditor" , "leading rank" , "Policeman; compliance official" , "reviewer" .)
