This book is, in part, based on the dramatic reconstruction of real people, identified by their actual names, and on fictional characters who sometimes embody features of people who existed at the time, but who are essentially fictional (see ‘Who is Who in the Book’). Where people who actually existed say anything substantial, their words are taken from documentary sources.
All the historical and politically substantial events depicted (and quite a few of the insubstantial events) are inspired by documentary sources.
But the book is, above all, a work of the imagination.
