night, about twelve o'clock
`` I think we 're going to have a storm after all , and a hard one , too . I 'm glad we 're safely anchored . '' Sure enough . That night , about twelve o'clock , the storm came . There was at first distant , muttering thunder , which soon became louder . Then lightning followed , flashing in through the windows of the houseboat , so that Mrs. Bobbsey was awakened . `` Oh , it 's going to be a terrible storm , '' she said to her husband .
