1934. When Daisy Wells and Hazel Wong set up a secret detective agency at Deepdean School for Girls, they struggle to find a truly exciting mystery to investigate. (Unless you count the case of Lavinia's missing tie. Which they don't.)

But then Hazel discovers the body of the Science Mistress, Miss Bell - but when she and Daisy return five minutes later, the body has disappeared. Now the girls have to solve a murder, and prove a murder has happened in the first place before the killer strikes again (and before the police can get there first, naturally).

But will they succeed? And can their friendship stand the test?

After the disastrous fallout on Halloween and the tragic events that followed in the Hazel Cove Cemetery, Alexandria is left picking up the pieces of her broken life. Peter is adjusting. James hates her. Grandma Claudia is gone. Emma is incoherent. Victor went rogue. And Gamma still wants her dead.

If that wasn't enough to deal with, two burning questions are driving Alex insane. Who committed that horrible murder in Salem? And what really happened to Ethan?

Alex has come to terms with her new life, but she's yet to truly understand the ramifications of being a pureblooded witch in the supernatural world. And now there is a new danger on the horizon. Alex must find a way to fight. To survive. To protect her remaining family members and her closest friends from an unthinkable new enemy. One much more powerful and much more horrifying than the Gamma witch hunting fraternity.

Light is chafing under L's extreme surveillance, but even 64 microphones and cameras hidden in his room aren't enough to stop Light.

He steps up the game, but before the battle of wits can really begin, a family emergency distracts him. But even though Light isn't using the Death Note right now, someone else is! Who's the new "Kira" in town?
