"Very much so indeed," replied Delapine, looking slyly at Renée, who blushed like a peony up to the roots of her hair.

"Ha, ha! I see, I see," said Villebois, slyly shaking his finger at them both. "Splendid, splendid," he cried. "Take care of her, Delapine, my boy, you have won the greatest treasure in all France. And you, my dear, have got a man who has not his equal anywhere. He is something more than a man, he is a hero, Renée. Mark my words, before we are two years older he will be the greatest savant in Europe. Give me your hands, both of you, and let me be the first to join them together. 'Pon my word, I think I am as pleased as either of you. But, not a word, not a word, eh, professor?"

"Thank you ever so much for your congratulations, doctor, and also for your hint of caution; were things otherwise, we should ask you to tell all the world, but under the circumstances it is better we should keep it strictly to ourselves. I have good reasons for believing that more than one person is anxious to separate us, and would do anything to get us out of the way."

"Do you really mean it, professor? I can't imagine that anyone would wish you evil. Surely you don't mean to say that you have enemies who come to my house?"

"It is not my habit to mention names, my dear doctor, but I assure you, you have a Judas among your disciples. Nay, you have two or three who would be delighted to see me dead."

"Come, my dear professor, you don't really mean that. You must be joking. Take the people who were at the dinner the other evening, Riche, Marcel, the Duvals, father and son. Surely they are all your friends and strictly honourable."

"Oh, yes! Brutus is an honourable man, so are they all, all honourable men," said Delapine, imitating the mocking sarcasm of Mark Antony.

"Are you not sarcastic, professor, or do you mean it?"

"Yes, doctor," Renée interposed, "Henri is right and he means it. Oh, I know it so well," she replied bitterly.

Henri squeezed her hand while she clung close to him for protection.
