"The Adventure of Wisteria Lodge" is one of the fifty-six Sherlock Holmes short stories written by Arthur Conan Doyle.
Holmes believes that the cryptic note came from this household and the writer could only be the house's governess, Miss Burnet, who has not been seen since the night of the murder.
It is revealed that "Henderson" is in fact Don Juan Murillo, an overthrown dictator from Central America who left a bloody trail behind as he escaped to England.
Her late husband was San Pedro's ambassador to Britain and a potential political rival to Murillo.
In the Strand, the story was published in two parts: "The Singular Experience of Mr. John Scott Eccles" and "The Tiger of San Pedro".
