However, when he had reached the cover of some trees he became conscious of his imprudence, and almost regretted the sudden madness which had borne him along, eager for escape.

Trembling nervously, he bent low among some furze bushes, and waited for a few minutes to ascertain if the police were behind him.

Then with watchful eye and ready ear, wonderful instinct and scent of danger, he slowly went his way again.

He hoped to pass between the upper lake and the Auteuil race-course; but there were few trees in that part, and they formed a broad avenue.

He therefore had to exert all his skill in order to avoid observation, availing himself of the slenderest stems, the smallest bushes, as screens, and only venturing onward after a lengthy inspection of his surroundings.
