A savage murder shocks London.
A clockmaker found dead in his shop, a steel spike driven clean through his skull.

Then another victim falls -- a policeman, killed the same way.
Both crimes committed behind locked doors. No sign of forced entry. No trace of the killer.

With terror mounting, only one man can unravel the mystery.
Sherlock Holmes must confront a deadly puzzle of time, treachery, and murder.
