"Villain! why didst thou not apprize me of this yesterday?" "A likely thing," said Hereward, "that I should feel myself at liberty to leave the ranks, and make such a communication to a man, whom, far from a friend, I then considered in the light of a personal enemy! Methinks, that instead of such language as this, you should be thankful that so many chance circumstances have at length brought me to befriend and assist you." Count Robert felt the truth of what was said, though at the same time his fiery temper longed to avenge itself, according to its wont, upon the party which was nearest at hand. But now they arrived at what the citizens of Constantinople called the Philosopher's Gardens. Here Hereward hoped to obtain entrance, for he had gained a knowledge of some part, at least, of the private signals of Achilles and Agelastes, since he had been introduced to the last at the ruins of the Temple of Isis. They had not indeed admitted him to their entire secret; yet, confident in his connexion with the Follower, they had no hesitation in communicating to him snatches of knowledge, such as, committed to a man of shrewd natural sense like the Anglo-Saxon, could scarce fail, in time and by degrees, to make him master of the whole. Count Robert and his companion stood before an arched door, the only opening in a high wall, and the Anglo-Saxon was about to knock, when, as if the idea had suddenly struck him,-- "What if the wretch Diogenes opens the gate? We must kill him, ere he can fly back and betray us. Well, it is a matter of necessity, and the villain has deserved his death by a hundred horrid crimes." "Kill him then, thyself," retorted Count Robert; "he is nearer thy degree, and assuredly I will not defile the name of Charlemagne with the blood of a black slave." "Nay, God-a-mercy!" answered the Anglo-Saxon, "but you must bestir yourself in the action, supposing there come rescue, and that I be over-borne by odds." "Such odds," said the knight, "will render the action more like a _melee_, or general battle; and assure yourself, I will not be slack when I may, with my honour, be active." "I doubt it not," said the Varangian; "but the distinction seems a strange one, that before permitting a man to defend himself, or annoy his enemy, requires him to demand the pedigree of his ancestor." "Fear you not, sir," said Count Robert. "The strict rule of chivalry indeed bears what I tell thee, but when the question is, Fight or not? there is great allowance to be made for a decision in the affirmative." "Let me give then the exorciser's rap," replied Hereward, "and see what fiend will appear." So saying, he knocked in a particular manner, and the door opened inwards; a dwarfish negress stood in the gap--her white hair contrasted singularly with her dark complexion, and with the broad laughing look peculiar to those slaves. She had something in her physiognomy which, severely construed, might argue malice, and a delight in human misery.
