I have now read 'Tunnel Trench'. The copy which you kindly gave me got lost—I don’t know how, but I obtained another one. . . . Of course the play is not ‘nice’ reading, and of course we who never went to the front in a fighting capacity hate to be reminded by those who did so go that there ever was a war. But all that does not matter. My criticism of the play, or of myself, would be that I cannot quite find the central moral idea upon which it is based.
