In the dawn of 1891 Sherlock Holmes is locked in a deadly game of wits with the sinister Professor James Moriarty; but events will soon transpire which will question the very outcome of Reichenbach. With Holmes presumed dead, the streets of London are panic-stricken, as a resurrected terror takes hold of the city; whilst in the upper-echelons of Government, a singular, undetectable force can once again be felt manipulating the criminal underworld. The ever reliable Dr. Watson has deceived us all, as he finally reveals the far more shocking events which led to both the return of Sherlock Holmes and his involvement in the suppression of London's most notorious criminal.
