Anatole France, in his satirical and allegorical fashion, weaves a tale of fantasy which finds a mischievous guardian angel stealing books from his earthly charge, who happens to be an archbishop in possession of a plethora of literature, mostly theological in nature. After voracious reading and then becoming a "fallen" angel, he decides to search for and recruit other "fallen" angels who devise a plan to attempt an overthrow of the rule which had set their fate, realizing that revolt is necessary and inevitable. What follows is preparation for a battle to revenge what has befallen them (and mankind itself). But surprises find their way into the plans, as well as the question that if they win the war, what will change? - Summary by Roger Melin
