"After strenuous exertions upon my part to recall to Leporello's mind the important question whether he had ever seen the true Duval, passing under the name of Marigny--whether she had not presented herself to his master at Vienna or elsewhere--he rubbed his forehead, and drew from it these reminiscences. "'On the day that his Excellency,'--Leporello generally so styled his master--'Excellency,' as you are aware, is the title an Italian would give to Satan if taking his wages,'told me that _la petite_ Marigny was no more, he had received previously a lady veiled and mantled, whom I did not recognise as any one I had seen before, but I noticed her way of carrying herself--haughtily--her head thrown back; and I thought to myself, that lady is one of his grandes dames. She did call again two or three times, never announcing her name; then she did not reappear. She might be Madame Duval--I can't say.' "'But did you never hear his Excellency speak of the real Duval after that time?' "'No--_non mi ricordo_--I don't remember.' "'Nor of some living Madame Marigny, though the real one was dead?' "'Stop, I do recollect; not that he ever named such a person to me, but that I have posted letters for him to a Madame Marigny--oh, yes! even years after the said _petite_ Marigny was dead; and once I did venture to say, 'Pardon me, Eccellenza, but may I ask if that poor lady is really dead, since I have to prepay this letter to her?'" "'Oh,' said he, 'Madame Marigny! Of course the one you know is dead, but there are others of the same name; this lady is of my family. Indeed, her house, though noble in itself, recognises the representative of mine as its head, and I am too _bon prince_ not to acknowledge and serve any one who branches out of my own tree.'" "A day after this last conversation on the subject, Leporello said to me: 'My friend, you certainly have some interest in ascertaining what became of the lady who took the name of Marigny (I state this frankly, Monsieur, to show how difficult even for one so prudent as I am to beat about a bush long but what you let people know the sort of bird you are in search of). "'Well,' said I, 'she does interest me. I knew something of that Victor de Mauleon, whom his Excellency did not wish to quarrel with; and it would be a kindly act to her relation if one could learn what became of Louise Duval.' "'I can put you on the way of learning all that his Excellency was likely to have known of her through correspondence. I have often heard him quote, with praise, a saying so clever that it might have been Italian, "Never write, never burn;" that is, never commit yourself by a letter-- keep all letters that could put others in your power. All the letters he received were carefully kept and labelled. I sent them to his son in four large trunks. His son, no doubt, has them still.'
