with me!  It has all been delightful, but there are excellent reasons why it should come to an end.”  “You have been playing a part, then,” he had gasped out; “you never cared for me?” “Yes; till I knew you; till I saw how far you would go.  But now the story’s finished; we have reached the denoument.  We will close the book and be good friends.”  “To see how far I would go?” he had repeated.  “You led me on, meaning all the while to do this!” “I led you on, if you will.  I received your visits, in season and out!  Sometimes they were very entertaining; sometimes they bored me fearfully.  But you were such a very curious case of—­what shall I call it?—­of sincerity, that I determined to take good and bad together.  I wanted to make you commit yourself unmistakably.  I should have preferred not to bring you to this place; but that too was necessary.  Of course I can’t marry you; I can do better.  So can you, for that matter; thank your fate for it.  You have thought wonders of me for a month, but your good-humour wouldn’t last.  I am too old and too wise; you are too young and too foolish.  It seems to me that I have been very good to you; I have entertained you to the top of your bent, and, except perhaps that I am a little brusque just now, you have nothing to complain of.  I would have let you down more gently if I could have taken another month to it; but circumstances have forced my hand.  Abuse me, curse me, if you like.  I will make every allowance!” Pickering listened to all this intently enough to perceive that, as if by some sudden natural cataclysm, the ground had broken away at his feet, and that he must recoil.  He turned away in dumb amazement.  “I don’t know how I seemed to be taking it,” he said, “but she seemed really to desire—­I don’t know why—­something in the way of reproach and vituperation.  But I couldn’t, in that way, have uttered a syllable.  I was sickened; I wanted to get away into the air—­to shake her off and come to my senses.  ‘Have you nothing, nothing, nothing to say?’ she cried, as if she were disappointed, while I stood with my hand on the door.  ‘Haven’t I treated you to talk enough?’ I believed I answered.  ‘You will write to me then, when you get home?’ ‘I think not,’ said I.  ‘Six months hence, I fancy, you will come and see me!’ ‘Never!’ said I.  ‘That’s a confession of stupidity,’ she answered.  ’It means that, even on reflection, you will never understand the philosophy of my conduct.’  The word ‘philosophy’ seemed so strange that I verily believe I smiled.  ‘I have given you all that you gave me,’ she went on.  ’Your passion was an affair of the head.’  ’I only wish you had told me sooner that you considered it so!’ I exclaimed.  And I went my way.  The next day I came down the Rhine.  I sat all day on the boat, not knowing where I was going, where to get off.  I was in a kind of ague of terror; it seemed to me I had seen something infernal.  At last I saw the cathedral towers here looming over the city.  They seemed to say something to me, and when the boat stopped, I came ashore.  I have been here a week.  I have not slept at night—­and yet it has been a week of rest!”
