Of Slain Kings on Checkered Fields
X Middle School's best hope to break a losing streak is Checkmatey, a flamboyant rapper who is X's finest chess player. Unfortunately, somebody is out to get him - is it Tyson Pelarez, leader of the Society of the Preservation of Ethics in Chess? Or is it Nelson Kelloch, Checkmatey's biggest rival? (Checkmatey also has a crush on Ingrid, which repulses her). Fillmore and Ingrid are on the case - but the clock is ticking down to the championship match and Checkmatey is nowhere to be found...
