(Michael Billington’s article appeared in the Guardian, 5/2.)
I cannot recommend too highly this play about the first world war by Allan Monkhouse, a former drama critic of the Manchester Guardian. Written in 1923, five years before RC Sherriff's infinitely more popular Journey's End, it strikes me as superior to the latter in every way: less emotionally reliant on public-school attitudes and more politically radical in its scepticism about war.
