For the first half hour, while the moon was still very brilliant and the night air very still, it seemed to Diogenes as if the loneliness around him was only fictitious, as if somewhere--far away mayhap--men moved in the same way as he did, swiftly and silently over the surface of the ice. It seemed to him in fact that he was being followed. He tried to make sure of this, straining his ears to listen, and now and then he caught very distinctly the sound of the metallic click of several pairs of skates. His senses, trained to over-acuteness through years of hard fighting and of campaigning, could not easily be deceived; and presently there was no doubt in his mind that Nicolaes Beresteyn or the Lord of Stoutenburg had set spies upon his track. This knowledge caused him only to set his teeth, and to strike out more vigorously and more rapidly than before; those who followed him were fairly numerous--over half a dozen he reckoned--the only chance of evading them was, therefore, in flight. He took to noting the rolling banks of cloud with a more satisfied eye, and when, after the first hour or so, the light of the waning moon became more dim and even at times disappeared completely, he took the first opportunity that presented itself of making a détour over a backwater of the Meer, which he knew must bewilder his pursuers. Whether the pursuit was continued after that, he could not say. His eyes trying to pierce the gloom could tell him nothing; but there were many intricate little by-ways just south of the Meer over backwaters and natural canals, which he knew well, and over these he started on an eccentric and puzzling career which was bound to baffle the spies on his track. Whenever he spoke subsequently of the many adventures which befell him during the first days of this memorable New Year, he never was very explicit on the subject of this night's run back to Houdekerk. As soon as he had rid himself--as he thought--of his pursuers, he allowed his mind to become more and more absorbed in the great problem which confronted him since he had pledged his word to Mynheer Beresteyn to bring the jongejuffrouw safely back to him. He now moved more mechanically over the iceways, taking no account of time or space or distance, only noting with the mere eye of instinct the various landmarks which loomed up from time to time out of the fast gathering darkness. This coming darkness he welcomed, for he knew his way well, and it would prove his staunch ally against pursuit. For the rest he was conscious neither of cold, of hunger nor of fatigue. Pleasant thoughts helped to cheer his spirits and to give strength to his limbs. His brief visit to Haarlem had indeed been fruitful of experiences. A problem confronted him which he had made up his mind to solve during his progress across the ice in the night. How to keep his word to Nicolaes Beresteyn, and yet bring the jongejuffrouw safely back to her father.
