“I am determined to make this girl my mistress,” said Henri to himself.

As he followed her along the terrace, in the direction of the Place Louis XV., he caught sight of the aged Marquis de San-Real, who was walking on the arm of his valet, stepping with all the precautions due to gout and decrepitude. Dona Concha, who distrusted Henri, made Paquita pass between herself and the old man.

“Oh, for you,” said De Marsay to himself, casting a glance of disdain upon the duenna, “if one cannot make you capitulate, with a little opium one can make you sleep. We know mythology and the fable of Argus.”

Before entering the carriage, the golden-eyed girl exchanged certain glances with her lover, of which the meaning was unmistakable and which enchanted Henri, but one of them was surprised by the duenna; she said a few rapid words to Paquita, who threw herself into the coupe with an air of desperation. For some days Paquita did not appear in the Tuileries. Laurent, who by his master’s orders was on watch by the hotel, learned from the neighbors that neither the two women nor the aged marquis had been abroad since the day upon which the duenna had surprised a glance between the young girl in her charge and Henri. The bond, so flimsy withal, which united the two lovers was already severed.

Some days later, none knew by what means, De Marsay had attained his end; he had a seal and wax, exactly resembling the seal and wax affixed to the letters sent to Mademoiselle Valdes from London; paper similar to that which her correspondent used; moreover, all the implements and stamps necessary to affix the French and English postmarks.

He wrote the following letter, to which he gave all the appearances of a letter sent from London:—

“MY DEAR PAQUITA,—I shall not try to paint to you in words the
passion with which you have inspired me. If, to my happiness, you
reciprocate it, understand that I have found a means of
corresponding with you. My name is Adolphe de Gouges, and I live
at No. 54 Rue de l’Universite. If you are too closely watched to
be able to write to me, if you have neither pen nor paper, I shall
understand it by your silence. If then, to-morrow, you have not,
between eight o’clock in the morning and ten o’clock in the
evening, thrown a letter over the wall of your garden into that of
the Baron de Nucingen, where it will be waited for during the
whole of the day, a man, who is entirely devoted to me, will let
down two flasks by a string over your wall at ten o’clock the next
morning. Be walking there at that hour. One of the two flasks will
contain opium to send your Argus to sleep; it will be sufficient
to employ six drops; the other will contain ink. The flask of ink
is of cut glass; the other is plain. Both are of such a size as
can easily be concealed within your bosom. All that I have already
done, in order to be able to correspond with you, should tell you
how greatly I love you. Should you have any doubt of it, I will
confess to you, that to obtain an interview of one hour with you I
would give my life.”

“At least they believe that, poor creatures!” said De Marsay; “but they are right. What should we think of a woman who refused to be beguiled by a love-letter accompanied by such convincing accessories?”

This letter was delivered by Master Moinot, postman, on the following day, about eight o’clock in the morning, to the porter of the Hotel San-Real.

In order to be nearer to the field of action, De Marsay went and breakfasted with Paul, who lived in the Rue de la Pepiniere. At two o’clock, just as the two friends were laughingly discussing the discomfiture of a young man who had attempted to lead the life of fashion without a settled income, and were devising an end for him, Henri’s coachman came to seek his master at Paul’s house, and presented to him a mysterious personage who insisted on speaking himself with his master.
