The third title in the brilliant series by Pamela Butchart.

Izzy and her friends have been plunged into more primary-school craziness. This time, they decide that their new head teacher is a vampire rat, based on his being slightly scary, having the blinds drawn in his office during the day and the fact he's banned garlic bread at lunchtimes.

Now they just have to come up with a plan to vanquish him....

Hilariously narrated by Susan Calman!
