Pianist Myra (4)
I believe the answer is:
hess
'pianist myra' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hess that I've seen before include "Famous pianist" , "Pianist Myra, Nazi Rudolf ---" , "Cite as evidence" , "leading Nazi" , "Rudolf ..., Nazi leader imprisoned at Spandau" .)
