Sir Arthur Conan Doyle

Sir Arthur Conan Doyle

According to the author Diane Madsen Sir Arthur Conan Doyle (creator of Sherlock Holmes) and his mentor Dr Joseph Bell correctly identified Jack the Ripper. Diane Madsen has released a new book detailing her beliefs: The Conan Doyle Notes: The Secret of Jack the Ripper.

Sir Arthur Conan Doyle was a clerk under Dr Joseph Bell at the Edinburgh Royal Infirmary during the late 1870s and credits the pioneering forensic scientist as a key inspiration for his literary detective and his renowned methods of deductive reasoning.

Scotland Yard used Dr Bell during the Jack the Ripper investigation - an investigation into the murders of five prostitutes in London's Whitechapel area in 1888.

Diane Madsen has been quoted as saying: "Bell said that he had a 'friend who liked puzzles', and they both investigated the files

"They researched everything and then they each wrote their suspect's name down on a piece of paper, put it in an envelope and exchanged envelopes – and they both identified the same suspect."

Ms Madsen insists Bell filed a report to Scotland Yard and also notes the murders stopped soon afterwards.

Ms Madsen says: "All of this fits in with there being some kind of a police conspiracy because the report was never publicised. It's no longer in the files, apparently, nobody has seen it, nobody has talked about it, yet he says he made a report."

Ms Madsen also believes it was the identity of their suspect which stopped Doyle and Bell from making their findings public. Ms Madsen believes they both suspected James K Stephen who was a tutor to Prince Albert Victor, son of the Prince of Wales.
