Yes, Rufus wrote Caius is a dumbell on his tablet at school. But no, he did not break into the schoolroom, did not tie up his teacher, and certainly did not paint his opinion of Caius on the Temple of Minerva (even if it is in Rufus's own handwriting).

But now Rufus is doomed.

Unless his six classmates can find out who is really responsible, Rufus will end up behind bars forever. Every hour seems to bring a new, confusing clue...until the boys finally stumble upon the real culprit.
