Manipulations. Misdirection. Mastermind. Loki and Lorelei's hunt for the mysterious Moriarty continues as the mind games become more perplexed. With breadcrumbs scattered along the way, the detective duo will find themselves hunting otherworldly ghosts, catching a menacing stalker, cracking the code in a suicide note and dealing with danger itself. Has the time finally come for the detectives to meet the manipulative mastermind face to face? The mystery resumes.

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.

Malice. Maneuvers. Masquerade. After being away from home for how many months, Lorelei confronts the past that has been haunting her as she gets involved in a series of unfortunate events in her previous high school and investigates the threat looming over her father's life. Back in Clark High, the mysterious shadow desperate for Moriarty's attention strikes again and takes more pawns on the chessboard. With the imminent danger coming at their doorstep, the Q.E.D club must put a stop on the senseless killing spree and gain the upper hand in their cat and mouse game against the young criminal mastermind. But as they face their most dangerous case yet, the unforeseen resolution might shock them to the core. Masks will fall off.

Menace. Misconception. Mendacity. Lorelei knows the truth about the man behind the shadows . . . or so it seems. After the shocking event at the abandoned building, the Q.E.D. Club is picking up the pieces in the hopes of being whole again. Loki is wounded. Jamie is traumatized. Alistair is in a coma. But recovery is not going to be that easy as an unseen yet familiar threat is looming over them. Again. Life goes on and cases as usual tend to follow the Q.E.D. Four. An “accidental” fire that consumed half of Tita Martha’s apartment, rumors about the so-called agent of death in a hospital, a baffling murder in a beach resort. And who expects them to spend an afternoon with the mastermind they have been trying to take down? Amidst the sea of mysteries and misdirection, another thread of attempted deception is ripe for unravelling.

Mistrust. Malfeasance. Majesty The QED four may have lost their club, but their friendship and legacy lives on. Now that they are back and complete again, it is time to face off with their most formidable opponent yet the editor-in-chief of the Clarion and one of Moriarty’s generals. Putting him in checkmate, however, is not going to be easy as he deflects their attacks and turns the tables on them. They also race against time as they attempt to prevent some secrets in Clark High from being exposed to the public. Should they fail, the campus will plunge into chaos. Among the people posing as their friends, a wolf hiding in sheep’s clothing finally reveals themselves.

Macabre. Mishap. Melancholy. Like a hydra’s head that keeps on growing back, the mystery that is Moriarty creates more questions than answers. After receiving a strange request from the self-proclaimed queen piece, the QED Club is conflicted about whether to trust her or not. They must find a way to retrieve from her the key that can bring down the organization in one fell swoop. But as they deal with that case, they must also deal with trust issues among themselves. Amid the seemingly endless cat-and-mouse chase, an unwelcome player makes the game more complicated than it already is. Are they a friend or a foe? One thing is for certain: This is the beginning of the end.

Mission. Madness. Memories. The time has come for the final act. The stage is set for the ultimate showdown between the QED Club and Moriarty's organization. After a series of shocking twists and unexpected turns, the cat-and-mouse chase between our high school detectives and the elusive mastermind has reached its endgame. The stakes are at their highest now. With the remaining pieces strategically positioned on the chessboard, it's only a matter of time before either side declares checkmate. When all is said and done, the curtain isn't the only thing falling. The end is near? The end is here.
