Dorothy sat for a long time without moving; then she drew a small writing-table up in front of her, and, taking a sheet of note-paper, began to write after a moment's hesitation. 'My dear Captain Armstrong,--When I saw you last I told you that I would let you know should the strange mystery of which I was the victim ever be cleared up. It is not yet entirely cleared up, but it is so to a considerable extent, as the woman who personated me has been traced to America, where she went a week after the robbery, and my portrait has been recognised as her likeness by a number of persons at the hotel where she stopped. This encourages us to hope that some day the whole matter will be completely cleared up. I received this news on the day after you left Chamounix, but I did not write to you before because I wanted to think over what you said to me in quiet. 'I have done so, and I am sorry, very sorry, Captain Armstrong, to say that I am certain my feelings towards you are not, and never will be, such as you desire. I like you, as I told you when you first asked me the question, very, very much, but I do not love you as you should be loved by a wife. I hope we shall always be good friends, and I wish you, with all my heart, the happiness you deserve, though I cannot be to you what you wish. I do not hesitate to sign myself your affectionate friend, Dorothy Hawtrey.' The note was written without pause or hesitation. It had been thought out before it was begun. It was strange, even to herself, how easily it had come to her, after having had it so much on her mind for the last month. She wondered now how she could have hesitated so long; how she could ever have doubted as to what she would say to him. 'I thank God I did not write before,' she murmured, as she directed the letter. 'I might have ruined my life and his, for, once done, I never could have drawn back again.' CHAPTER XX A caravan--consisting of ten waggons, drawn by teams of six, eight, and ten bullocks, five or six lighter vehicles of various descriptions, half-a-dozen horsemen, and a score of men on foot--was making its way across an undulating plain. Few words were spoken, for what was there to talk of when one day was but a picture of another? The women, sitting for the most part in the waggons, knitted or worked with but an occasional remark to each other. The men, walking with the oxen, kept on their way as doggedly as the animals they drove, and save for the occasional crack of a whip or a shout from one of the men to his beasts, and the occasional creaking of a wheel, the procession might have seemed to an onlooker a mere phantasmagoria of silent shapes. But the sun was getting low and the oxen beginning almost insensibly to quicken their pace, and all knew that the long day's journey was nearly over, and the water-holes could not be far ahead.
