One little chinchilla loves going to visit her Auntie Iris.
But there's danger in the air at the block of flats where she lives. . . not surprising when there are bears on the first floor, crocodiles on the second floor and wolves on the third!
Then one day, Auntie Iris goes down to put out the rubbish, and she doesn't come back! Little Chinchilla is determined to solve the mystery of her disappearance, even if it does mean talking to her very scary neighbours!
