four o'clock
Between four and five was an hour when Viola was very apt to come in . In the instant that followed the posting of that letter I saw what I had done . And I wrote to him the next day asking him to dinner , in order that he should not come in between four and five . For some weeks , whenever I fancied he was about due at four o'clock , I wrote and asked him to dinner . That was how I fastened him to me . There was n't any sense in which he fastened on me . I was n't by any means his only hope .
