Amateur sleuths will be able to solve the mystery of Arthur Conan Doyle’s “The Adventure of the Illustrious Client”, when the original version of the manuscript goes on display next month at the Museum of London. The manuscript was bequeathed to the Scottish nation in the will of Conan Doyle’s daughter, but it’s been held in a vault at a bank in London, out of public view, while Scottish museums vied for the honour of displaying it. After the author’s death in 1930, the manuscript was inherited by his daughter, Dame Jean Conan Doyle who died at the age of 84 in 1997. The true identity of the “illustrious client” of the title, the man who comes to ask Sherlock Holmes and Dr. Watson for discreet help, is famously never revealed to the reader in the story. Once the manuscript goes on display, devoted Holmes-ians will be able to search for clues laid out in Conan Doyle’s own handwriting.
