Mandy Hope loves animals more than anything else. She knows quite a lot about them too: both her parents are vets and Mandy helps out in their surgery, Animal Ark.
James is given the school hamster to look after in the summer holidays. He and Mandy are delighted - until someone vandalises James's garden and steals the poor hamster. Who is to blame? The city kids from the caravan park - or someone closer to home?
