As ten o'clock was striking, d'Artagnan left M. de Treville, who thanked him for his information, recommended him to have the service of the king and queen always at heart, and returned to the saloon; but at the foot of the stairs, d'Artagnan remembered he had forgotten his cane. He consequently sprang up again, re-entered the office, with a turn of his finger set the clock right again, that it might not be perceived the next day that it had been put wrong, and certain from that time that he had a witness to prove his alibi, he ran downstairs and soon found himself in the street.
