Chap involved in noted war drama (6)
I believe the answer is:
edward
'chap' is the definition.
(I've seen this before)
'involved in noted war drama' is the wordplay.
'involved in' indicates a hidden word.
'EDWARD' can be found hidden inside 'noted war drama'.
(Other definitions for edward that I've seen before include "The Black Prince" , "-- Lear; -- Heath" , "Former King" , "Boy's name" , "-- Lear, poet" .)
