The naughtiest girl marches on : the further adventures of Enid Blyton's naughtiest girl

The continued adventures of the Naughtiest Girl - as written by Anne Digby, author of Trebizon.

Elizabeth is overjoyed to be appointed monitor again, especially when the new head-boy and girl have such exciting ideas.

But one of the second form boys is slowly turning all the other boys against her, starting with a nasty note in her desk and ending with a false tip-off about a midnight pillow fight in the boys' dormitory.

Rather than report it, Elizabeth plans to investigate - and, with the help of some friends, unleash a surprise waterpistol attack on the boys.

But Elizabeth has been set up, as she discovers when she runs straight into their form teacher and the head boy - mistakenly squirting them both with water.

Now, Elizabeth is in trouble again - and she could lose her prized monitor's role.

Can she find out who has a grudge against her - and why?
