Examination someone's suspiciously late for? (7)
I believe the answer is:
autopsy
'examination' is the definition.
(autopsy is a kind of examination)
'someone's suspiciously late for?' is the wordplay.
I cannot really understand how this works, but
'for?' could be 'to' (eg both can mean 'in the opinion of') and 'to' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for autopsy that I've seen before include "Dissection of a body to determine the cause of death" , "Examining body" , "Examination to determine cause of death" , "An official post-mortem examination" , "Post-mortem inspection" .)
