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 a 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 halfway 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.
