Arrived at the end of the lane, d'Artagnan turned to the left.

The house in which Aramis dwelt was situated between the Rue Cassette and the Rue Servandoni.
D'Artagnan had just passed the Rue Cassette, and already perceived the door of his friend's house, shaded by a mass of sycamores and clematis which formed a vast arch opposite the front of it, when he perceived something like a shadow issuing from the Rue Servandoni.

This something was enveloped in a cloak, and d'Artagnan at first believed it was a man; but by the smallness of the form, the hesitation of the walk, and the indecision of the step, he soon discovered that it was a woman.

Further, this woman, as if not certain of the house she was seeking, lifted up her eyes to look around her, stopped, went backward, and then returned again.

D'Artagnan was perplexed.
"Shall I go and offer her my services ?" thought he.
