D'Artagnan slipped into the wardrobe.

Hardly was he concealed when the little bell sounded.
Kitty went to her mistress, and did not leave the door open; but the partition was so thin that one could hear nearly all that passed between the two women.
Milady seemed overcome with joy, and made Kitty repeat the smallest details of the pretended interview of the soubrette with de Wardes when he received the letter; how he had responded; what was the expression of his face; if he seemed very amorous.

And to all these questions poor Kitty, forced to put on a pleasant face, responded in a stifled voice whose dolorous accent her mistress did not however remark, solely because happiness is egotistical.
Finally, as the hour for her interview with the count approached, Milady had everything about her darkened, and ordered Kitty to return to her own chamber, and introduce de Wardes whenever he presented himself.
Kitty's detention was not long.

Hardly had d'Artagnan seen, through a crevice in his closet, that the whole apartment was in obscurity, than he slipped out of his concealment, at the very moment when Kitty reclosed the door of communication.
"What is that noise ?" demanded Milady.
"It is I," said d'Artagnan in a subdued voice, "I, the Comte de Wardes." "Oh, my God, my God!" murmured Kitty, "he has not even waited for the hour he himself named!" "Well," said Milady, in a trembling voice, "why do you not enter?
Count, Count," added she, "you know that I wait for you." At this appeal d'Artagnan drew Kitty quietly away, and slipped into the chamber.
If rage or sorrow ever torture the heart, it is when a lover receives under a name which is not his own protestations of love addressed to his happy rival.

D'Artagnan was in a dolorous situation which he had not foreseen.
