Have you ever seen a ghost, Mr. Holmes?“ asks Victoria Temple, and Sherlock Holmes, at the height of his powers in 1898, must face a new challenge, one that plunges the great detective into the realm of the supernatural. Miss Temple has been found guilty—but also insane—at her trial for murdering a child under her care. She is locked away in the Broadmoor lunatic asylum and, worse still, she believes fully in her own guilt. <br /><br />But were the hauntings at the Elizabethan manor house of Bly a vision of the walking dead, perhaps, rather than delusions of her tormented mind? Or could it be that a criminal conspiracy is to blame for the psychic phenomena? In the company of Dr. Watson, the indefatigable Holmes will track down the perpetrators through the occult underworld of Victorian London.
