"The Adventure of the German Student" is a short story by Washington Irving, which was published in 1824 in his collection of essays Tales of a Traveller.
[1] In regards to "The Adventure of the German student", Irving writes that "the story, or rather than the latter part of it, is founded on an anecdote related to me as existing somewhere in the French".
At the end of the story, the incident is revealed to have been recounted by "the old gentleman with the haunted head", and is said to have been relayed by Wolfgang, who now resides in a madhouse in Paris.
Alexandre Dumas implemented a similar plot for his 1851 story "La femme au collier de velours", or "The woman with the velvet necklace".
A variation of the story appears under the title "The Velvet Ribbon" in the 1970 children's book Ghostly Fun by Ann McGovern.
[6] Carmen Maria Machado offers a reworking of the tale as the short story "The Husband Stitch" in her collection Her Body and Other Parties.
