Theo the mouse has led a rather sheltered life on a dusty shop shelf, but this soon changes when he becomes a Christmas present. Arriving at his new home, Theo finds himself surrounded by mystery, adventure and a host of colourful characters who turn his simple life upside down and make him realise what it truly means to be a mouse. The Chronicles of a Rodent is a series composed of six short stories that follow the life and adventures of the noble and courageous mouse, Theodore. This introductory instalment contains the first two of these stories.

Theo the mouse is about to embark on another adventure. The reader is invited to follow him as he explores his new home, meets new friends and is reluctantly drawn into a gravely mysterious adventure.
