Before event, old magistrate enters
I believe the answer is:
reeve
If this is the answer, I'm afraid I cannot explain it.
Can you help me to learn more?
(Other definitions for reeve that I've seen before include "Steward who told a Tale" , "Female ruff - Canterbury tale-teller" , "estate supervisor" , "Female ruff; also a bailiff" , "Former magistrate" .)
