On 5 December 5 1941, two days before the Japanese attack on Pearl Harbor, Virgil Thomson wrote to Gertrude Stein, his friend and the cocreator of their opera Four Saints in Three Acts. The bulk of the letter concerned Thomson's most recent plan for publication of the opera, including details of dividing the royalties and expenses involved in the undertaking (a continual source of disagreement and haggling between them). At the end of the letter, referring to Stein's assurance at the end of her most recent letter to him that the European war would be over soon and that they would soon meet again in Paris, Thomson wrote, ‘… I miss you a great deal but do hope that you are right that we shall be seeing each other soon in Paris. I wouldn't know; I have no prophetic sense about wars … When the war is over we must write another opera. Only we must wait till then, because I don't think we could choose the subject very well by mail'. His next preserved letter to her was almost five years later. In that letter, dated 5 March 1946, Thomson wrote, ‘Carl [Van Vechten] says the opera is nearly finished. I hope so. I want to see it. I pine for it’.
