Stake stuck into companion by old woman in drama (7)
I believe the answer is:
macbeth
'drama' is the definition.
(I have seen 'bloody drama' mean 'macbeth' so perhaps 'drama' could also mean 'macbeth')
'stake stuck into companion by old woman' is the wordplay.
'stake' becomes 'bet' ('bet' can be a synonym of 'stake').
'stuck into' indicates putting letters inside.
'companion' becomes 'ch' (I've seen this in other clues).
'by' means one lot of letters go next to another.
'old woman' becomes 'ma' (I've seen this in other clues).
'bet' going within 'ch' is 'cbeth'.
'cbeth' put after 'ma' is 'MACBETH'.
'in' is the link.
(Other definitions for macbeth that I've seen before include "piece" , "Shakespeare play" , "Scottish ruler" , "its name must not be mentioned" , "King of Scotland, 1040-1057" .)
