From A Bibliography of Alexandre Dumas père by Frank Wild Reed: One of the series of "Chronique-romans."
The period is that of a lull in the Hundred Years' War, 1385 to 1391.
Sub-title: "Chronique dans laquelle est racontée l'Histoire du Démon Familier du Sire de Corasse." ("Chronicle in which is related the Story of the Familiar Demon of the Sire de Corasse.")
It originally ran as a serial through the pages of "Le Siècle."
Its first appearance in book form was as part of the second volume of the first (French) edition of "Acté."
It is now included in the standard Calmann-Lévy edition as part of the final volume of "Salvator."
In Le Vasseur's "Alexandre Dumas Illustré" it occupies part of Vol. VIII.
