'Ah--what then? You look concerned.' 'Old times have come to life, owing to something waking them.' 'Old times be cursed--which old times are they?' 'That Christmas week twenty-two years ago, when the late Duchess's cousin Frederick implored her to meet him on Marlbury Downs. I saw the meeting--it was just such a night as this--and I, as you know, saw more. She met him once, but not the second time.' 'Mills, shall I recall some words to you--the words of an oath taken on that hill by a shepherd-boy?' 'It is unnecessary. He has strenuously kept that oath and promise. Since that night no sound of his shepherd life has crossed his lips--even to yourself. But do you wish to hear more, or do you not, your Grace?' 'I wish to hear no more,' said the Duke sullenly. 'Very well; let it be so. But a time seems coming--may be quite near at hand--when, in spite of my lips, that episode will allow itself to go undivulged no longer.' 'I wish to hear no more!' repeated the Duke. 'You need be under no fear of treachery from me,' said the steward, somewhat bitterly. 'I am a man to whom you have been kind--no patron could have been kinder. You have clothed and educated me; have installed me here; and I am not unmindful. But what of it--has your Grace gained much by my stanchness? I think not. There was great excitement about Captain Ogbourne's disappearance, but I spoke not a word. And his body has never been found. For twenty-two years I have wondered what you did with him. Now I know. A circumstance that occurred this afternoon recalled the time to me most forcibly. To make it certain to myself that all was not a dream, I went up there with a spade; I searched, and saw enough to know that something decays there in a closed badger's hole.' 'Mills, do you think the Duchess guessed?' 'She never did, I am sure, to the day of her death.' 'Did you leave all as you found it on the hill?' 'I did.' 'What made you think of going up there this particular afternoon?' 'What your Grace says you don't wish to be told.' The Duke was silent; and the stillness of the evening was so marked that there reached their ears from the outer air the sound of a tolling bell. 'What is that bell tolling for?' asked the nobleman. 'For what I came to tell you of, your Grace.' 'You torment me it is your way!' said the Duke querulously. 'Who's dead in the village?' 'The oldest man--the old shepherd.' 'Dead at last--how old is he?' 'Ninety-four.' 'And I am only seventy. I have four-and-twenty years to the good!' 'I served under that old man when I kept sheep on Marlbury Downs. And he was on the hill that second night, when I first exchanged words with your Grace. He was on the hill all the time; but I did not know he was there--nor did you.' 'Ah!' said the Duke, starting up. 'Go on--I yield the point--you may tell!'
