One carrying out his duty to the letter? (7)
I believe the answer is:
bailiff
This clue might be a double definition.
'one carrying' is the first definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'out his duty to the letter?' is the second definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
Can you help me to learn more?
(Other definitions for bailiff that I've seen before include "Landlord's agent or steward" , "Officer of court" , "Law officer who helps sheriff, say to foreclose" , "Landowner's agent" , "Possibly menacing landlord's agent" .)
