midnight
She had not seen Lady Heyburn that day . She had seen no one . At six o'clock that morning she had written a long letter to Walter Murie . She had not mentioned the midnight incident , but she had , with many expressions of regret , pointed out the futility of any further affection between them . She had not attempted to excuse herself . She merely told him that she considered herself unworthy of his love , and because of that , and that alone , she had decided to break off their engagement . A dozen times she had reread the letter after she had completed it .
