On Aug. 14, 1924, after a third night of sold-out houses at the Abbey Theater in Dublin, inveterate Irish playgoer Joseph Holloway noted in his diary: “The Shadow of a Gunman [has] been staged for three nights with the usual result—that crowds had to be turned away each performance. . . . Certainly [Sean O’Casey] has written the two most popular plays ever seen at the Abbey, and they both are backgrounded by the terrible times we have just passed through, but his characters are so true to life and humorous that all swallow the bitter pill of fact that underlies both pieces.”
