CLAMP School is not just a school - it's a self-contained city. Housing 10,000 students from Kindergarten to Graduate level, it facilitates education for anyone talented, regardless of wealth. At the elementary level, three students lead the student council: Nokoru, the youngest son of the company that built the school; Suoh Takamura, the cool-headed secretary; and Akira, both a talented cook and the council's treasurer. Well-liked and resourceful, the trio is able to help the fairest of damsels with ease. And thus, after saving a sad old woman, Nokoru decides to create the CLAMP School Detective Agency; their goal, to help out any maiden in distress!
CLAMP School Detectives is rather lighter than Utena (though this version of the Utena story isn't as heavy as most of the others), but if you enjoyed the over-the-top decadence of the giant, exclusive schools that either of these manga are set in, or the bishounen-heavy student council (Utena's cast also includes some very princely ladies, as well), and mystery elements of one, you'll probably enjoy the other.

Princess Knight was one of the earliest shoujo manga, and had a huge influence on subsequent shoujo stories. This influence is especially apparent in works like Utena, that also uses crossdressing and princely female characters as major plot points.
