Narrated by Laurence Bouvard and Edward Petherbridge. A lovely American actress awakens in London on a cold morning in 1897 - lying face down on the concrete pavement outside the British Museum. She has no memories. She does not even know who she is, although she has a vague recollection of the name Sherlock Holmes. What she believes is that she has may have just killed someone, and that someone is definitely trying to kill her. As she searches for clues to her true identity, she will learn that she is not the only target. Unless she can defeat her evil adversaries, the people most dear to her will die.
