German count’s friend’s final resting place (9)
I believe the answer is:
palsgrave
'german count's' is the definition.
(count of the Holy Roman Empire)
'friend's final resting place' is the wordplay.
'friend's' becomes 'pals' (pal is a kind of friend).
'final resting place' becomes 'grave'.
'pals'+'grave'='PALSGRAVE'
(Other definitions for palsgrave that I've seen before include "Noble" , "Count" , "Old lord" .)
