The extraordinary adventures of Arsène Lupin, gentleman-burglar

The various incidents, which I shall record in writing at a later day, have established between us certain ties.... shall I say of friendship? Yes, I venture to believe that Arsène Lupin honors me with his friendship, and that it is through friendship that he occasionally calls on me, and brings, into the silence of my library, his youthful exuberance of spirits, the contagion of his enthusiasm, and the mirth of a man forwhom destiny has naught but favors and smiles.
