Heartbreak House is not merely the name of the play which follows this preface. It is cultured, leisured Europe before the war. When the play was begun not a shot had been fired; and only the professional diplomatists and the very few amateurs whose hobby is foreign policy even knew that the guns were loaded. A Russian playwright, Tchekov, had produced four fascinating dramatic studies of Heartbreak House, of which three, The Cherry Orchard, Uncle Vanya, and The Seagull, had been performed in England.
