“But not until two o’clock,” said D’Artagnan, with the same calmness.

“But what are you going to fight about, Athos?” asked Aramis.

“Faith! I don’t very well know. He hurt my shoulder. And you, Porthos?”

“Faith! I am going to fight—because I am going to fight,” answered Porthos, reddening.

Athos, whose keen eye lost nothing, perceived a faintly sly smile pass over the lips of the young Gascon as he replied, “We had a short discussion upon dress.”

“And you, Aramis?” asked Athos.

“Oh, ours is a theological quarrel,” replied Aramis, making a sign to D’Artagnan to keep secret the cause of their duel.

Athos indeed saw a second smile on the lips of D’Artagnan.

“Indeed?” said Athos.

“Yes; a passage of St. Augustine, upon which we could not agree,” said the Gascon.
