This book is a celebration of all things Agatha Raisin. It includes an introduction by M C Beaton, Agatha's biography, her background and retirement to the Cotswolds, her complex love life and the details of village life in Carsely.

There are brief biogs of all the men in her life (there are many), a piece on her cats Hodge and Boswell, and a section on Agatha's Cotswolds, both real and fictitious. Plot summaries of all twenty titles in the series, a quiz to test your Agatha knowledge and a selection of her favourite dishes in Raisin's Recipes rounds off the complete Agatha Companion.

It also features line drawings by Alice Tait - the artist of the all new covers in the Agatha Raisin series - throughout.
