with hours and hours to fill (

plus *sigh*), I'm just thinking about the quarter of clues not yet done.
13 across is: tragic royal's damaged pectoral area (9)
Letters: - - E - P - E - A
It's one of those clues that has come up before and I think it is an anagram of pectoral plus possibly R? But a hint would be much appreciated, please.
ETA Went straight back to CCTV and thought CLEOPATRA - should have thought of this already....
