Flaxman Low is a fictional character created by British authors Hesketh Hesketh-Prichard and his mother Kate O'Brien Ryall Prichard, published under the pseudonyms "H. Heron" and "E. Heron". Low is credited with being the first psychic detective of fiction, and appears in a series of short stories.
Flaxman Low is a pseudonym for “one of the leading scientists of the” Victorian era, whose real name is not disclosed in the stories. He was an accomplished athlete in his youth and has turned his interests to a scientific study of the occult.
From 1898-1899 press baron Cyril Arthur Pearson published six Flaxman Low stories in his monthly Pearson's Magazine, though the authors were disconcerted to find the tales promoted by Pearson as "real". The collected work was published as The Experiences of Flaxman Low in 1899.
The stories are as follows:
"The Improbable Adventures of Sherlock Holmes" (2009) includes a short story by author Barbara Roden, "The Things That Shall Come Upon Them" which teams up Flaxman Low with Sherlock Holmes who together investigate a haunted house mystery.
