Arsene Lupine once told me these eight adventures. He attributed them to his friend, Prince Renin. But, taking into account the character of the hero and his actions, you involuntarily come to the conclusion that Lupine and Prince Renin are one and the same person. It must be taken into account that Lupine is such an original that sometimes he denies his participation in the adventure, although he was its hero, and sometimes he is able to take credit for actions that he did not commit. But let the reader judge for himself.
