Young Sherlock Holmes

Eccentric consulting detective Sherlock Holmes and Doctor John Watson battle to bring down a new nemesis and unravel a deadly plot that could destroy England.

There is a new criminal mastermind at large (Professor Moriarty) and not only is he Holmes’ intellectual equal, but his capacity for evil and lack of conscience may give him an advantage over the detective.

When a nobleman is threatened by a family curse on his newly inherited estate, detective Sherlock Holmes is hired to investigate.

Holmes and Watson board a passenger train bound from London to Edinburgh, to guard the Star of Rhodesia, an enormous diamond worth a fortune belonging to an elderly woman of wealth; but within the first hour of the trip, the woman's son is murdered and the diamond stolen and any of the passengers in their car could be the killer thief.
