A journey through a garden in the town, where Max Ernst was born. Max Ernst was a surrealist and this book tries to be surrealistic by combining things that might not fit at first view. The title of the book is on one hand a citation of a famous story called "un semaine de bonte" (a story with surrealistic character) and on the other hand the name of the Author "Ernst" (engl. "seriousness") is translated into the french word "serieux". Does not make sense? Definitely maybe.
