“What are you saying?” she shrilled. “D'ye hear the filthy fellow, Rotherby? He'll not name the wanton in my presence out of respect for her.”

“For shame, madam! You are speaking of his mother,” cried Hortensia, hot with indignation.

“Pshaw! 'Tis all an impudent lie—a pack of lies!” cried Rotherby. “He's crafty as all the imps of hell.”

Mr. Caryll rose. “Here in the sight of God and by all that I hold most sacred, I swear that what I have said is true. I swear that Lord Ostermore—your father—was my father. I was born in France, in the year 1690, as I have papers upon me that will prove, which you may see, Rotherby.”

His lordship rose. “Produce them,” said he shortly.

Mr. Caryll drew from an inner pocket of his coat the small leather case that Sir Richard Everard had given him. From this he took a paper which he unfolded. It was a certificate of baptism, copied from the register of the Church of St. Antoine in Paris.

Rotherby held out his hand for it. But Mr. Caryll shook his head. “Stand here beside me, and read it,” said he.

Obeying him, Rotherby went and read that authenticated copy, wherein it was declared that Sir Richard Everard had brought to the Church of St. Antoine for baptism a male child, which he had declared to be the son of John Caryll, Viscount Rotherby, and Antoinette de Maligny, and which had received in baptism the name of Justin.

Rotherby drew away again, his head sunk on his breast. Her ladyship was seated, her eyes upon her son, her fingers drumming absently at the arms of her chair. Then Rotherby swung round again.

“How do I know that you are the person designated there—this Justin Caryll?”
