Sir Arthur Conan Doyle: Clues in the Wellcome Library (UK)

From The Wellcome Library blog: "We started 2010 with a post on material from our collections which had been opened under the Data Protection Act, on the case of Charles H.M. Kerr: from our records, patient of Manor House Asylum in Chiswick, but identified - after a little detective work of our own - as illustrator of some of Conan Doyle's Sherlock Holmes stories. Now, on the day of the 80th anniversary of Sir Arthur Conan Doyle's death, we can announce the release material with a more direct connection to Conan Doyle himself: letters written by Sir Arthur himself. Whilst relatively minor pieces of correspondence, these letters have made us ponder the other material in the Wellcome Library's collections with a link to Conan Doyle: clues that when put together offer a portrait of the creator of the most famous of all fictional detectives"
