Boy Genius Plays A Dangerous Game

The Macintosh Jewelry building is Lupin's next target, but he quickly finds himself having to rescue a kidnapped boy. This is no ordinary boy though; his is the keeper of revolutionary scientific research. He also happens to be a huge fan of Lupin and as much of a lecher as Lupin. How can Lupin stop Macintosh from stealing the boy's secrets, steal Macintosh's inventory, and keep himself from getting slapped for the boy's penchant for peeking up women's skirts?
