All done except 30a, 'Lord and servants frequently grasp the meaning of Cooper's autobiography'. Unless I am mistaken, at least one 'o' is omitted from the wordplay.
Also cannot parse 33a.
Also for the endgame - I take it to mean that you solve the clashes by restoring the 'heads' of the 'outlaws', although I suppose in theory you could intepret it the other way (off with their heads as it were). Thoughts? Many thanks.
I think you replace the individual heads for the common clashing letter in all of them (which is an abbrev for the second word of the shaded definition).
