("Pardon my French"! I am a Frenchwoman and so am likely to make mistakes in writing this review)
I bought this item with the FALSE idea that some of the short stories had actuall been written by Mark Gatiss or Stephen Fry. It is strongly implied (in ambiguous terms though) on the cover. Yet they made a contribution... to the "Introduction". I can't blame them for not getting more involved - they pretty much have other things to do - but I blame the publisher, who did a fairly poor job. Indeed, in addition to this, some of the texts had mispellings, erros in typography etc. Which is too bad, because otherwise it is a fairly enjoyable book!
Those were the drawbacks. If you are a fan of Sherlock Holmes and want to (or not) to support the preservation of Conan Doyle's house, go ahead! Some stories are quite brillant (I think of "Distraction" or "Charlie Milverton"); not all are set in Victorian times, a few (budding?) writers used the BBC series as a basis for their story... A couple of them are actually set in the future! And let's not forget about the moving poems dedicated to Holmes or Doyle. Of course, as they are very different from one another, you might not appreciate every single one of them; but still, you have a good time and discovers new aspects to Holmes' or Watson's peronality or life.
