This book is all about the mystery behind Michelangelo's artwork, and it's no wonder that Konigsburg picked this particular artist to focus on. Michelangelo is considered one of the great masters of the Renaissance. We know that Claudia would never settle for anything but the best, so of course the kids are teaching themselves facts and history on one of the greatest artists of all time. Even Mrs. Frankweiler says so—and we're pretty sure she knows what she's talking about.
And oh yeah, they see Marie Antoinette's chair (2.50) and stay in a bed that was the scene of a historical murder (3.54). Thrilling!
