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.
