''Holmes,'' I cried.''Is it really you? Can it indeed be that you are alive? Is it possible that you succeeded in climbing out of that awful abyss?'' Missing, presumed dead, for three years, Sherlock Holmes returns triumphantly to his dear companion Dr Watson. And not before time! London has never been in more need of his extraordinary services: a murderous individual with an air gun stalks the city. Among thirteen further brilliant tales of mystery, detection and deduction, Sherlock Holmes investigates the problem of the Norwood Builder, deciphers the message of the Dancing Men, and cracks the case of the Six Napoleons.
