“Egad, didn’t you hear? these horses belong to Monsieur de Montbazon; well, Monsieur de Montbazon is the husband of Madame de Montbazon——”

“And——”

“And Madame de Montbazon is the mistress of the Duc de Beaufort.”

“Ah! I understand,” replied Porthos; “she has ordered relays of horses.”

“Exactly so.”

“And we are pursuing the duke with the very horses he has just left?”

“My dear Porthos, you are really a man of most superior understanding,” said D’Artagnan, with a look as if he spoke against his conviction.

“Pooh!” replied Porthos, “I am what I am.”

They rode on for an hour, till the horses were covered with foam and dust.

“Zounds! what is yonder?” cried D’Artagnan.
