twelve o'clock
`` You are alone ? '' `` No one had approached the place since I came here a quarter of an hour ago . '' `` It is time for action , '' the horseman said . `` To-morrow you will come boldly at twelve o'clock to my house , and demand to see me on important business . You will be shown to my room , where two officers who I wish to have as witnesses will be present . You will then state to me that you wish to make a denunciation of your master , Count Preskoff . I shall ask what you have to say , and tell you that you are of course aware of the serious consequences to yourself should such statements be proved untrue .
