The person walked rapidly along, threading the intricate and obscure streets, without hesitation; every now and then, however, drawing his cloak closer around him, and casting a hurried look behind, as if to observe if he was followed. On these occasions, Groff contrived to shrink under the shade of some buttress, or projecting wall. Owing to his being perfectly well acquainted with the streets, and knowing each turning the person would probably take, he was enabled, successfully to dodge his footsteps, till he had arrived in the neighbourhood of the mansion previously described, in the garden of which the meetings of the conspirators were held. The man there stopped, and looked cautiously around, retracing his steps for a short distance, as if to assure himself that he had not been followed; throwing a scrutinising glance, as he lifted his hand to shade his eyes, down two or three narrow lanes, which there turned off from that along which he had passed. He seemed, however, satisfied, and was about to pass on. "Now is my time," thought Groff, who had hidden beneath a dark arch way, "I will now rush forward, and strike him, to make sure, and save myself a long and disagreeable watch; but he looks as if prepared for danger, and I may find a warmer reception than I wish, or he may cry out and give the alarm, before I have time to escape." While Groff was thus debating with himself, the person again walked on, unconscious of the danger he had so narrowly just escaped; and the assassin, fearful of being discovered after his evident wariness, if he pursued him further, concealed himself carefully under an arch, let into a wall, which had at one time served as an entrance to the garden behind it; but, for some reason, the inner part was now blocked up with stones, leaving, however, a recess sufficiently deep for a person to hide within it. "Here I will await his return," muttered Groff; "he has never yet failed to pass this way, and I have well marked his figure, so that I should know him if there was but a glimpse of light. I wish I had followed him to find out where he goes to, for there may be some secret worth knowing in that. It is an odd place for a person to come to so constantly, and I should make a fine thing of it, if I discovered any hidden plot, which the Count could reveal to the Emperor; it would bring him into high favour, and I, his follower, would benefit by it. I might easily manage to get rid of the youth in some other place, and if I slay him now, I lose my opportunity. But no! one scheme is but a chance, while his death will give me a certainty of reward."
