M.P.'s quarry (4)
I believe the answer is:
awol
'mp's quarry' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for awol that I've seen before include "Truant (or just missing)" , "Absent without leave (abbrev.)" , "Missing without permission" , "Army offence of being missing from duty, briefly" , "Of soldier, illegally absent - initially" .)
