Machinations. Minions. Mudslinging.

The identity of the elusive Moriarty has been revealed, but the case is still far from over.
With a new member joining their ranks, the QED club continues to solve cases in Clark High, decosing a missing writer's peculiar poems, disarming bombs that threaten the school, and putting an end to the "Twinkle, Twinkle" murders.

Amidst the moves and countermoves between the club and the mastermind's gang, a shadow lurks in the dark; waiting for the opportune moment to strike.

The real chase has just begun.
