His costume of Guardsman in the company of M.
Dessessart ought to be his passport.
He therefore went down the Rue des Petits Augustins, and came up to the quay, in order to take the New Bridge.

He had at first an idea of crossing by the ferry; but on gaining the riverside, he had mechanically put his hand into his pocket, and perceived that he had not wherewithal to pay his passage.
As he gained the top of the Rue Guenegaud, he saw two persons coming out of the Rue Dauphine whose appearance very much struck him.

Of the two persons who composed this group, one was a man and the other a woman.
The woman had the outline of Mme.Bonacieux; the man resembled Aramis so much as to be mistaken for him.
Besides, the woman wore that black mantle which d'Artagnan could still see outlined on the shutter of the Rue de Vaugirard and on the door of the Rue de la Harpe; still further, the man wore the uniform of a Musketeer.
The woman's hood was pulled down, and the man held a handkerchief to his face.

Both, as this double precaution indicated, had an interest in not being recognized.
They took the bridge.

That was d'Artagnan's road, as he was going to the Louvre.
