Andrea Sperelli followed him with his eyes till he crossed the threshold of the room. The moment he was alone, unspeakable anguish rent his soul. This room, hung with dark-red damask, exactly like the one in which Elena had received him two years ago, seemed to him tragic and sinister. These were, perhaps, the very same hangings that had heard Elena say to him that day, 'I love you.' The book-case was open, and he could see the rows of obscene books, the bizarre bindings stamped with symbolic decorations. On the wall hung the portrait of Lady Heathfield side by side with a copy of Sir Joshua Reynolds's Nelly O'Brien. And the two women looked out of the canvas with the same, self-same piercing intensity, the same glow of passion, the same flame of sensual desire, the same marvellous eloquence; each had a mouth that was ambiguous, enigmatical, sibylline, the mouth of the insatiable absorber of souls; and each had a brow of marble whiteness, immaculately, radiantly pure.

'Poor Redgrave!' said Lord Heathfield, returning with the portfolio of drawings. 'There was a genius for you. There never was an erotic imagination to equal his. Look! look! What style! What profound knowledge of the potentialities of the human figure for expression.'

He left Andrea's side for a moment in order to close the door. Then he returned to the table in the window and began turning over the collection under Sperelli's eyes, talking without a pause, pointing out with that ape-like finger the peculiar characteristics of each figure.

He spoke in his own language, beginning each sentence with an interrogative intonation and ending with a monotonous irritating drop of the voice. Certain words lacerated Andrea's ear like the sound of filing iron or the shriek of a steel knife over a pane of glass.

And the drawings passed in review before him, appalling pictures which revealed the terrible fever that had taken hold upon the artist's hand, and the terrible madness that possessed his brain.

'Now here,' said Lord Heathfield, 'is the work which inspired these masterpieces. A priceless book—rarest of the rare! You are not acquainted with Daniel Maclisius?'

He handed Andrea the treatise: De verberatione amatoria. He had warmed more and more to his subject. His bald temples were flushed, and the veins stood out on his great forehead; every minute his mouth twitched a little convulsively and his hands, those detestable hands, were perpetually on the move, while his arms retailed their paralytic immobility. The unclean beast in him appeared in all its brazen ugliness and ferocity.

'Mumps! Mumps! are you alone?'

It was Elena's voice. She knocked softly at one of the doors.

'Mumps!'
