Napoleon’s Double, by Antoni Jach, is another in the series of fictions inspired by the larger-than-life figure of Napoleon Bonaparte. It would be wrong, however, to think that this is an historical novel about Napoleon the man. The operative word in the title is the word ‘double’, and the imaginative writing in the novel ‘doubles’ history, illuminating it. Doubles abound in the work: of the characters, but also of central themes and meanings.
