I asked him if he had known her long.

'Twelve months,' he answered. 'I lodged on the fifth, madame on the second, floor of the same house in Paris.'

I leaned forward and plucked the hem of his black robe. 'What is this?' I said, with a little contempt. 'You are not a priest, man.'

'No,' he answered, fingering the stuff himself, and gazing at me in a curious, vacant fashion. 'I am a student of the Sorbonne.'

I drew off from him with a muttered oath, wondering--while I looked at him with suspicious eyes--how he came to be here, and particularly how he came to be in attendance on my mother, who had been educated from childhood in the Religion, and had professed it in private all her life. I could think of no one who, in old days, would have been less welcome in her house than a Sorbonnist, and began to fancy that here should lie the secret of her miserable condition.

'You don't like the Sorbonne?' he said, reading my thoughts; which were, indeed, plain enough.

'No more than I love the devil!' I said bluntly.

He leaned forward and, stretching out a thin, nervous hand, laid it on my knee. 'What if they are right, though?' he muttered, his voice hoarse. 'What if they are right, M. de Marsac?'

'Who right?' I asked roughly, drawing back afresh.

'The Sorbonne,' he repeated, his face red with excitement, his eyes peering uncannily into mine. 'Don't you see,' he continued, pinching my knee in his earnestness, and thrusting his face nearer and nearer to mine, 'it all turns on that? It all turns on that--salvation or damnation! Are they right? Are you right? You say yes to this, no to that, you white-coats; and you say it lightly, but are you right? Are you right? Mon Dieu!' he continued, drawing back abruptly and clawing the air with impatience, 'I have read, read, read! I have listened to sermons, theses, disputations, and I know nothing. I know no more than when I began.'
