I desiring him so to do, he went on thus: I being in this manner, said he, revenged of one Mistress, did resolve to leave her off quite, lest she should in time pay me off in my own Coin, and did endeavour to get another, but could not meet with or find any to my mind; but I and one of those of my acquaintance who had assisted me in my late exploit, one day talking of our female friends, told me that indeed, although he had not gain’d so much by a Mistress at once as I had done by mine, yet he had such a Mistress as had bin not only pleasing, but very profitable to him, for said he, I can command fifty or a hundred Crowns at any time; I marry Sir, said I, that is a good Mistress indeed, and is more than ordinary; yes replyed he, she is no ordinary person. I hearing him say so, knew it was to no purpose to ask her Name and Quality, but did resolve so to watch him that I would find it out, I usually therefore kept him Company and like his shadow still attended him, but he being as cunning as I was crafty, so privately mannag’d his amours, that I could not possibly find him out, I therefore sometimes lay with him, and took the opportunity of searching his Pockets for Letters, but found none, so that I was very doubtful of attaining my Ends, which was to discover who this unknown invisible Lady was, I finding that my acquaintance was too close to get any thing out of, was resolved to take another course, and since I could not out-wit the Master, try if my Boy could out-wit his; I therefore instructed my Boy in what he was to do, and ordered him to get in with the other, and get out of him one time or other, whether he did not carry Letters to any Persons, and to whom. My Boy was not so long about his Discovery as I had been about mine, for in a short time he told me that the Boy was often employed to carry Letters to a Mercers Maid, who lived in the next street, and also to a Carrier who conveyed Letters to an Unkle; I now partly knowing the Who, was desirous of knowing the What, and therefore ordered my Boy by one means or other to get one of his Letters and bring it unto me. He so well discharged himself in this employ, that it was not long e’re he brought me one. I being very curious to know the Contents, soon opened it, for heating a Knife in the fire, I put it under the Seal, which melted the Wax in that place, and so it was open, wherein I found these expressions. Madam, I _am very sorry that I am so unfortunate, that in the term of fourteen days I have not had the happiness of waiting on you, sure the old man is grown jealous, or which is worse, you begin to slight me, or else some expedient might have been found to have deceived him: I shall say no more at present, referring the rest of my Complaints till I see you, which happy minute I beseech you hasten, or else you will very much afflict_ _Your constant Friend_, S.
