"Ah," said Monnier, "I dare say neither Madame de Grantmesnil nor even Rousseau ever even guessed the ideas they awoke in their readers; but one idea leads on to another. And genuine poetry and romance touch the heart so much more than dry treatises. In a word, Madame de Grantmesnil's book set me thinking; and then I read other books, and talked with clever men, and educated myself. And so I became the man I am." Here, with a self- satisfied air, Monnier bowed to the Englishman, and joined a group at the other end of the room. The next evening, just before dusk, Graham Vane was seated musingly in his own apartment in the Faubourg Montmartre, when there came a slight knock at his door. He was so wrapped in thought that he did not hear the sound, though twice repeated. The door opened gently, and M. Lebeau appeared on the threshold. The room was lighted only by the gas-lamp from the street without. Lebeau advanced through the gloom, and quietly seated himself in the corner of the fireplace opposite to Graham before he spoke. "A thousand pardons for disturbing your slumbers, Monsieur Lamb." Startled then by the voice so near him, Graham raised his head, looked round, and beheld very indistinctly the person seated so near him. "Monsieur Lebeau?" "At your service. I promise to give an answer to your question; accept my apologies that it has been deferred so long. I shall not this evening go to our cafe. I took the liberty of calling--" "Monsieur Lebeau, you are a brick." "A what, Monsieur!--a brique?" "I forgot; you are not up to our fashionable London idioms. A brick means a jolly fellow, and it is very kind in you to call. What is your decision?" "Monsieur, I can give you some information, but it is so slight that I offer it gratis, and forego all thought of undertaking further inquiries. They could only be prosecuted in another country, and it would not be worth my while to leave Paris on the chance of gaining so trifling a reward as you propose. Judge for yourself. In the year 1849, and in the month of July, Louise Duval left Paris for Aix-la-Chapelle. There she remained some weeks, and then left it. I can learn no further traces of her movements." "Aix-la-Chapelle! What could she do there?" "It is a Spa in great request; crowded during the summer season with visitors from all countries. She might have gone there for health or for pleasure." "Do you think that one could learn more at the Spa itself if one went there?" "Possibly. But it is so long,--twenty years ago." "She might have revisited the place." "Certainly; but I know no more." "Was she there under the same name,--Duval?" "I am sure of that." "Do you think she left it alone or with others? You tell me she was awfully belle; she might have attracted admirers."
