Yes, he's a very interesting man - wrote a lot of historical novels besides Sherlock. There's a neat bio of him at the The Conan Doyle Society (http://www.ash-tree.bc.ca/acdsbio.html). Tried to do a search for Cremona and Doyle - got mostly violin stuff! Guess It will have to wait for a visit to the library - darn, I must prefer instant gratification!
