Many thanks to Roger Johnson of the Sherlock Holmes Society of London for the following notice:

A plaque will be unveiled at the Langham on March 19th, 2010. It reads:

Oscar Wilde and Arthur Conan Doyle dined here with the publisher of Lippincott’s Magazine on 30 August 1889, a meeting that led to The Sign of Four & The Picture of Dorian Gray”

Both stories were published in Lippincott’s, a Philadelphia-based magazine, in 1890.

Also from Roger Johnson: There are plans to convert “Undershaw”, ACD’s home at Hindhead, into flats. Please go to http://undershawhelp.blogspot.com for updated information and what you can do to prevent this.
