She looked straight before her, for whenever she glanced at the road-side, and her eye was caught by some dried up shrub of the desert, silvery in the pale moonlight, she fancied she saw behind it the face of a murderer.
The skeletons of fallen beasts standing up out of the dust, and the bleached jawbones of camels and asses, which shone much whiter than the desert-sand on which they lay, seemed to have come to life and motion, and made her think of the tiger-teeth of the bearded ruffian.
The clouds of dust driven in her face by the warm west wind, which had risen higher, increased her alarm, for they were mingled with the colder current of the night-breeze; and again and again she felt as if spirits were driving her onwards with their hot breath, and stroking her face with their cold fingers.

Every thing that her senses perceived was transformed by her heated imagination into a fearful something; but more fearful and more horrible than anything she heard, than any phantom that met her eye in the ghastly moonlight, were her own thoughts of what was to be done now, in the immediate future--of the fearful fate that threatened the Roman and Irene; and she was incapable of separating one from the other in her mind, for one influence alone possessed her, heart and soul: dread, dread; the same boundless, nameless, deadly dread--alike of mortal peril and irremediable shame, and of the airiest phantoms and the merest nothings.
A large black cloud floated slowly across the moon and utter darkness hid everything around, even the undefined forms which her imagination had turned to images of dread.

She was forced to moderate her pace, and find her way, feeling each step; and just as to a child some hideous form that looms before him vanishes into nothingness when he covers his eyes with his hand, so the profound darkness which now enveloped her, suddenly released her soul from a hundred imaginary terrors.
She stood still, drew a deep breath, collected the whole natural force of her will, and asked herself what she could do to avert the horrid issue.
Since seeing the murderers every thought of revenge, every wish to punish the seducer with death, had vanished from her mind; one desire alone possessed her now--that of rescuing him, the man, from the clutches of these ravening beasts.

Walking slowly onwards she repeated to herself every word she had heard that referred to Publius and Irene as spoken by Euergetes, Eulaeus, the recluse, and the assassins, and recalled every step she had taken since she left the temple; thus she brought herself back to the consciousness that she had come out and faced danger and endured terror, solely and exclusively for Irene's sake.

The image of her sister rose clearly before her mind in all its bright charm, undimmed by any jealous grudge which, indeed, ever since her passion had held her in its toils had never for the smallest fraction of a minute possessed her.
Irene had grown up under her eye, sheltered by her care, in the sunshine of her love.
