Victor Hugo

“ Appetite grows with loving. To know that her name was Ursule was a great deal; it was very little. In three or four weeks, Marius had devoured this bliss. He wanted another. He wanted to know where she lived.
He had committed his first blunder, by falling into the ambush of the bench by the Gladiator. He had committed a second, by not remaining at the Luxembourg when M. Leblanc came thither alone. He now committed a third, and an immense one. He followed "Ursule."
She lived in the Rue de l'Ouest, in the most unfrequented spot, in a new, three-story house, of modest appearance. ”

“ On the next day they did not come to the Luxembourg. Marius waited for them all day in vain.
At nightfall, he went to the Rue de l'Ouest, and saw a light in the windows of the third story.
He walked about beneath the windows until the light was extinguished.
The next day, no one at the Luxembourg. Marius waited all day, then went and did sentinel duty under their windows. This carried him on to ten o'clock in the evening.
His dinner took care of itself. Fever nourishes the sick man, and love the lover.
He spent a week in this manner. M. Leblanc no longer appeared at the Luxembourg. ”

“ One evening, after he had followed them to their dwelling, and had seen them disappear through the carriage gate, he entered in their train and said boldly to the porter:--
"Is that the gentleman who lives on the first floor, who has just come in?"
"No," replied the porter. "He is the gentleman on the third floor." ”
