One day when he was well-nigh in the heart of the swamp of Lambeth he saw a figure making his way across. The hour was already late and the night was falling, and the appearance of the man was so different from that of the usual denizens of the swamp that Walter wondered what business there might be. Scarcely knowing why he did so, Walter threw himself down among some low brushwood and watched the approaching figure. When he came near he recognized the face, and saw, to his surprise, that it was a knight who had but the day before stopped at the armourer's shop to have two rivets put in his hauberk. He had particularly noticed him because of the arrogant manner in which he spoke. Walter had himself put in the rivets, and had thought, as he buckled on the armour again, how unpleasant a countenance was that of its wearer. He was a tall and powerful man, and would have been handsome had not his eyes been too closely set together; his nose was narrow, and the expression of his face reminded Walter of a hawk. He had now laid aside his helmet, and his figure was covered with a long cloak. “He is up to no good,” Walter said to himself, “for what dealings could a knight honestly have with the ruffians who haunt these swamps. It is assuredly no business of mine, but it may lead to an adventure, and I have had no real fun since I left Aldgate. I will follow and see if I can get to the bottom of the mystery.” When he came close to the spot where Walter was lying the knight paused and looked round as if uncertain of his way. For four or five minutes he stood still, and then gave a shout of “Humphrey” at the top of his voice. It was answered by a distant “Hallo!” and looking in the direction from which the answer had come, Walter saw a figure appear above some bushes some four hundred yards distant. The knight at once directed his steps in that direction, and Walter crept cautiously after him. “A pest upon these swamps and quagmires,” the knight said angrily as he neared the other. “Why didst not meet me and show me the way through, as before?” “I thought that as you had come once you would be able to find your way hither again,” the man said. “Had I thought that you would have missed it I would have come ten times as far, rather than have had my name shouted all over the country. However, there is no one to hear, did you shout thrice as loud, so no harm is done.” “I thought I saw a figure a short time since,” the knight said. The man looked round in all directions. “I see none,” he said, “and you may have been mistaken, for the light is waning fast. It were ill for anyone I caught prying about here. But come in, sir knight; my hovel is not what your lordship is accustomed to, but we may as well talk there as here beneath the sky.”
