Enter Sherlock Holmes museum! 221 B on Baker Street. A very small museum, with scenes from various A. Conan Doyle books reenacted in wax in rooms furnished as they would be, had Sherlock Holmes and Dr. Watson really lived and worked there. One of the more amazing expositions of the museum (not shown here) is a collection of letters that different people (mostly kids) wrote to Sherlock Holmes, together with answers actually written by the museum staff. I read most of them, and had only one slight problem: there is a letter there from a kid, about some "old guy who's mean to kids", who really is the infamous prof. Moriarty, and who is riding a certain bus route at a certain time. There is also a serious and understanding answer written by somebody at the museum saying that that guy is really prof. Moriarty's son, and that the police keep a close watch over him. The only problem: the answer is dated more than a year earlier than the letter itself! Made me wonder about the authenticity of all those letters...
