London. Last century.
Watson is rebuffed by Sherlock Holmes, when he shares his concern about his friend's health, because more and more Holmes resorts to drugs, cocaine. In these times Homes and Watson get an assignment by the Royal Family: The family's reputation is in jeopardy - just before the wedding of the royal prince. Papers exist indicating that a memeber of the royal family was involved with another woman and are about to be made public. Out of that relationship a girl had been born, but she died. Holmes' task is to retrieve the papers secretly.

The whereabouts of the papers are known by a young Lady, Alice Faulkner. She is held captive by James and Madge Larrabee, a criminal couple, who try to get hold of the papers. So far they have not been able to force Alice to give away the knowledge she has.
Holme's efforts have to be absolutely discreet. The fact that his most severe enemy, Professor Moriarty, is asked by the Larrabees to help them does not make things easier. Moriarty won't leave out any chance to destroy Holmes. Several times Moriarty tries to kill him, but Holmes always survives, often thanks to his unique talents and sometimes by pure luck. Holmes succeeds in retrieving the papers and recues Alice. Both fall in love with each other - this changes Holmes drastically so that Watson's worries have an end.
