The Great Hamster Massacre

This is a story about me, and Tom, and our investigation into the Hamster Massacre. I'm supposed to be writing my What-I-Did-In-The-Summre-Holidays story for school, but I'm going to write this story first...Anna and het brother, Tom, have always wanted a pet. After their latest pestering campaign Mum finally gives in and lets them choose a pair of hamsters from the local pet shop. But their happiness soon turns to horror when they discover the hamsters mysteriously slaughtered in their cage. Anna and Tom begin an investigation into the hamster homicides. Can they solve the case of the Great Hamster Massacre?
