Post-mortem examination (7)
I believe the answer is:
autopsy
'post-mortem examination' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for autopsy that I've seen before include "final critical analysis" , "Examination to determine cause of death" , "An official post-mortem examination" , "Post-mortem inspection" , "Far from quick examination" .)
