"Donald Thomas is the all-time best at Sherlockian pastiche." —Ellery Queen Mystery Magazine "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.   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.
