D'Artagnan followed Milady without being perceived by her.
"Amuse yourself with Milady, my dear D'Artagnan; I wish you may with all my heart, if that will amuse you."
Meantime, he was going to try to find out Milady. Milady had spoken to the man in the black cloak; therefore she knew him.
At the end of an instant's observation he heard the noise of a vehicle, and saw Milady's carriage stop opposite to him.
Milady put her charming blond head out at the window, and gave her orders to her maid.
"Oh!" said D'Artagnan, "this is rather warm; it appears that Milady and I are anxious about the health of the same person.
The conversation between Milady and the cavalier was so animated that D'Artagnan stopped on the other side of the carriage without anyone but the pretty SOUBRETTE perceiving his presence.
The cavalier laughed aloud, which appeared to exasperate Milady still more.
At the first word Milady turned, looking at the young man with astonishment; and when he had finished, she said in very good French, "Monsieur, I should with great confidence place myself under your protection if the person with whom I quarrel were not my brother."
"Milady," she declared, "has never, no never, appeared more charming.
"Milady thinks herself a trifle pale, perhaps--a little more color?"
"Milady knows very well what becomes her," the woman answered discreetly.
