"Readers...will find themselves stretching their powers of deduction." --Booklist

After a student turns up murdered on Bonfire Night, Hazel and Daisy find themselves entrenched in another mystery in this delightfully charming fourth novel of the Wells & Wong Mystery series.

Daisy Wells and Hazel Wong have returned to Deepdean School for Girls for a new school term, but nothing is the same. There's a new Head Girl, Elizabeth Hurst, and a team of Prefects--and these bullying Big Girls are certainly not good eggs.

Then, after the fireworks display on Bonfire Night, Elizabeth is found--murdered.

Many girls at Deepdean had reason to hate Elizabeth, but who could have committed such foul play? Is the murder linked to the secrets and scandals, scribbled on the scraps of paper that are suddenly appearing all over the school? And with their own friendship falling to pieces, will Daisy and Hazel be able to solve this mystery before suspicions tear the student body apart?
