"Go alone, then!" said Martin. "I have looked on't once and live." CHAPTER XI THE strange glance of hatred the burgomaster had cast on Gerard, coupled with his imprisonment, had filled the young man with a persuasion that Ghysbrecht was his enemy to the death: and he glided round the angle of the tower, fully expecting to see no supernatural appearance, but some cruel and treacherous contrivance of a bad man to do him mischief in that prison, his escape from which could hardly be known. As he stole forth, a soft but brave hand crept into his, and Margaret was by his side to share this new peril. No sooner was the haunted tower visible, than a sight struck their eyes that benumbed them as they stood. More than half way up the tower, a creature with a fiery head, like an enormous glowworm, was steadily mounting the wall: the body was dark, but its outline visible through the glare from the head, and the whole creature not much less than four feet long. At the foot of the tower stood a thing in white, that looked exactly like the figure of a female. Gerard and Margaret palpitated with awe. "The rope, the rope! It is going up the rope," gasped Gerard. As they gazed, the glowworm disappeared in Gerard's late prison, but its light illuminated the cell inside and reddened the window. The white figure stood motionless below. Such as can retain their senses after the first prostrating effect of the supernatural, are apt to experience terror in one of its strangest forms, a wild desire to fling themselves upon the terrible object. It fascinates them as the snake the bird. The great tragedian Macready used to render this finely in Macbeth at Banquo's second appearance. He flung himself with averted head at the horrible shadow. This strange impulse now seized Margaret. She put down Gerard's hand quietly, and stood bewildered; then, all in a moment, with a wild cry, darted towards the spectre. Gerard, not aware of the natural impulse I have spoken of, never doubted the evil one was drawing her to her perdition. He fell on his knees. "Exorcizo vos. In nomine beatæ Mariæ, exorcizo vos." While the exorcist was shrieking his incantations in extremity of terror, to his infinite relief he heard the spectre utter a feeble cry of fear. To find that hell had also its little weaknesses was encouraging. He redoubled his exorcisms and presently he saw the ghastly shape kneeling at Margaret's knees and heard it praying piteously for mercy. Kate and Giles soon reached the haunted tower. Judge their surprise when they found a new rope dangling from the prisoner's window to the ground. "I see how it is," said the inferior intelligence, taking facts as they came. "Our Gerard has come down this rope. He has got clear. Up I go, and see."
