Michael Kurland has written a series of novels in which Moriarty is the hero: His organisation of crime is the method by which he raises the money required for his experimental physics apparatus. In the first book of the series, The Infernal Device, he foils a plot against Queen Victoria, reluctantly allying with Sherlock Holmes.

In Death by Gaslight, blue blood is flowing in London as a killer slits the throats of the cream of England's aristocracy. Naturally Scotland Yard enlists the great Sherlock Holmes himself. Only when this ultimate weapon of the law failed to stem the deaths are they forced to play a last desperate card - Professor James Moriarty, the Napoleon of Crime.
