A decent collection of short stories with the premise of Sherlock Holmes interacting with various sci-fi elements. The book is divided into 3 categories. Holmes in the present(His time), Holmes in the future (Anytime after what would be his lifetime) and Holmes after death (Just what it sounds like).
None of these stories hold a candle to Conan Doyle of course but they are amusing for the most part. One story has Holmes being contacted by time travellers to find out why the Titanic DIDN'T sink, another has him solving serial murder cases in modern day California and future Mars and still another suggests that Holmes was never a flesh and blood man but was the first computer program rudimentary AI.
Of all the stories only one was what I would consider weak. That being Dogs, Masques, Love, Death: Flowers by Barry N. Malzberg. This one story's connection to Holmes is so tenous as to be almost nonexistant and the whole story is a bit disjointed.
But overall the collection is a fun light read for those who enjoy both Science Fiction and the stories of the Greatest Detective of all Time.
