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. Sherlock Holmes, the gaunt, ascetic, ruthlessly logical pursuer of crime and mystery created by Sir Arthur Conan Doyle, needs no introduction. The adventures of this sharply witty and Moody detective and his lovable pedantic and faithful friend Dr. Watson are a perennial source of inspiration to lovers of crime fiction.
