A fantastic character (challenger) in a nice novel that precedes of pleasant fantastic news (or science fiction). It includes alas not the charm of the first 12 new Sherlock Holmes, let's be honest. However, Conan Doyle's admirers should be aware of the many stories contained in this book whose style did not blush but offers O how uneven content that hardly happens if you have previously run in the reading of all the fantastic work of Maupassant. It seems that Conan Doyle best imitated Poe Jules Vernes, in short.
