From Reviews (ADR) by Arthur D. Rypinski:
Horror novella with supernatural shock ending. Dumas' hero in this
short novel is a historical figure, the 17-year old future composer,
musician, and romantic writer Ernst Theodor Hoffmann, best known for
today for writing the short story on which Tchaikovsky based "The
Nutcracker Suite" (see Histoire d'un casse-noisette) and for Offenbach's "Tales of Hoffman." In a lengthy
introduction, Dumas' avers that this story was originally told to him by
his friend Charles Nodier, whose adventures during the terror Dumas
chronicled in Les Blancs et les Bleus.
Young Hoffmann sets out from Mannheim to visit Paris in 1793, at the
height of the terror, having first promised his fiancée that he will not
gamble and that he will be true to her.
Hoffmann arrives in Paris just in time to witness the guillotining of
Madame du Barry, quandam mistress of Louis XV, and plunged into shock,
attends the theatre where he is captivated by the the beautiful Arsène,
danseuse and mistress of Danton, one of the architects of the terror.
Hoffmann is poor, and must gamble to win enough money to win Arsène.
But meanwhile, the terror threatens to swallow Danton and his mistress.
An unusual product for Dumas, in which the reader is never sure whether
what is real, what is supernatural, and what is product of Hoffmann's
growing madness. Also, a vivid portrait of Paris enmeshed in the
terror.
From A Bibliography of Alexandre Dumas père by Frank Wild Reed: The last of the stories belonging to the "Mille et un Fantômes." Like the others, it has an occult setting, and Dumas takes for his hero the German writer of fantastic tales, Hoffmann. The plot is the same as that of Washington Irving's "The Lady with the Velvet Collar; or, the Adventure of the German Student," but it is very doubtful if Dumas drew from Irving, rather in all probability both drew from a common source. The contrast between the two narratives is well worth noting. Further, Dumas once again equips his story with one of those always charming introductory passages, in this instance Nodier's house at the Arsenal Library. It is Nodier, Dumas claims, and probably quite correctly in this instance, who first told him the story.
The scene is Paris, in the days of the guillotine, period 1793, and the death of Mme. Dubarry is graphically described.
It first ran as a serial in "Le Constitutionnel."
Original edition : Paris, Cadot, 2 vols., 8vo., 1851.
Vol. I., pp. 326 and table of contents.
Vol. II., pp. 353 and table of contents.
It now forms one volume in the standard Calmann-Lévy edition, part of one in their illustrated series, and one in their "Musée Littéraire."
In Le Vasseur's "Alexandre Dumas Illustré" it forms, with the rest of the "Mille et un Fantômes," part of Vol. XVII.
