Murderer's Love

«I've lived on my own since I was a small child, at least until I took in Gavroche. I never knew my parents and have lived on the streets my whole life, which has hardened my heart. I often get told that I have a stone-heart or frozen-heart, which is true for all except one little person. When most people see me they think that I'm an almost respectable young lady, due to how well dressed I often am, but what the don't know is that they are looking at one of Paris' most wanted criminals, second only to Montparnasse. I've committed all but one crime at the age of 18 and have been to prison once, though they could only contain me for half a night before I escaped. To the law, and many citizens, I'm known as 'Mademoiselle' and among many criminals, I'm called 'Rose of the Underworld', due to my looks. The reason that they don't call me by my first name is simply that they don't know it. Only one living person knows my name, and that person is my adopted younger brother, Gavroche. »

Can this murderess ever learn to love anyone other than her little brother?
