<P> In the fourth and final act , outdoors behind the home , the soldiers , who by now are friends of the family , are preparing to leave the area . A flash - photograph is taken . There is an undercurrent of tension because Solyony has challenged the Baron ( Tuzenbach ) to a duel , but Tuzenbach is intent on hiding it from Irina . He and Irina share a heartbreaking delicate scene in which she confesses that she can not love him , likening her heart to a piano whose key has been lost . Just as the soldiers are leaving , a shot is heard , and Tuzenbach 's death in the duel is announced shortly before the end of the play . Masha has to be pulled , sobbing , from Vershinin 's arms , but her husband willingly , compassionately and all too generously accepts her back , no questions asked . Olga has reluctantly accepted the position of permanent headmistress of the school where she teaches and is moving out . She is taking Anfisa with her , thus rescuing the elderly woman from Natasha . </P>
