Schoolgirl detectives Daisy Wells and Hazel Wong are at Daisy's home, Fallingford, for the holidays. Daisy's glamorous mother is throwing a tea party for Daisy's birthday, and the whole family is invited, from eccentric Aunt Saskia to dashing Uncle Felix. But it soon becomes clear that this party isn't really about Daisy at all. Naturally, Daisy is furious.

Then one of their party falls seriously, mysteriously ill - and everything points to poison.

With wild storms preventing anyone from leaving, or the police from arriving, Fallingford suddenly feels like a very dangerous place to be. Not a single person present is what they seem - and everyone has a secret or two. And when someone very close to Daisy looks suspicious, the Detective Society must do everything they can to reveal the truth . . . no matter the consequences.

Robin Stevens was born in California and grew up in an Oxford college, across the road from the house where Alice in Wonderland lived. She has been making up stories all her life.

When she was twelve, her father handed her a copy of The Murder of Roger Ackroyd and she realised that she wanted to be either Hercule Poirot or Agatha Christie when she grew up. When it occurred to her that she was never going to be able to grow her own spectacular walrus moustache, she decided that Agatha Christie was the more achievable option.

She spent her teenage years at Cheltenham Ladies’ College, reading a lot of murder mysteries and hoping that she’d get the chance to do some detecting herself (she didn’t). She then went to university, where she studied crime fiction, and now she works at a children’s publisher, which is pretty much the best day job she can imagine.

Robin now lives in Cambridge with her boyfriend and her pet bearded dragon, Watson.
