Corday's victim, 1793 (5)
I believe the answer is:
marat
'corday's victim 1793' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for marat that I've seen before include "Jean Paul -, assassinated French revolutionary" , "French revolutionary killed by Charlotte Corday" , "Jean Paul, French revolutionary, murdered in his bath" , "French revolutionary killed in his bath" , "French revolutionary politician" .)
