Don't know if anyone has discovered it yet but there is a new novel out there based or should I say, 'related'... to the famous sleuth. It's called 'The fruits of Bohemia' por author Bill Cornwell ('Residents of Wardate' ).
The título gives us the first clue in what develops into an in depth adventure in present time. Can't give the game away too much. Needless to say there are murders, abductions and romance all intertwined in what proves to be a book difficult to put down. It's available on Kindle at the moment for 99p - it might even be free. Don't miss it!
