Boniface, nicknamed "Bo", is a main character in The Thief Lord.
Boniface (a.k.a. Bo) lived with his brother, Prosper, and his mother. When his mother died, he was adopted by his aunt and uncle, Esther and Max Hartlieb, thus separating him from his brother (who he could then only see once a month). Then, when Prosper decides to bring Bo to a place where their mother fantasized about, they ran away from Hamburg to Venice. Bo is about 5 years old according to the book.
- Main article: The Thief Lord (novel)
After Bo had moved to Venice with his brother, Prosper, he expected a happy life with his new friends without his cruel aunt Esther coming to find him again. When Bo is then being followed by a detective, Victor Getz, he knows he will have to be sent back to his aunt and uncle. But when Victor and Bo grow a strong bond together, Victor stalls and tells Esther that the boys are no longer in Venice. Bo grows a liking of stealing.
Bo, unlike his brother Prosper, is rather childish and is eager to join the rest of the gang out stealing. Unlike Prosper, he is worry-free and thinks that him and Prosper are safe in Venice. He believes that they are a safe distance from their aunt Esther.
He is described with angelic features, having curly blond hair which is later dyed black with ink in an attempt to render Bo unrecognisable by Victor Getz.
