“So you know House-on-the-Hill, Mr. Terhune?”Local bookseller and amateur detective Theodore Terhune is asked to investigate the history of an ancient Kentish manor house for its new owner, Dr. Vincente Salvaterra. Recently arrived from Panama, Salvaterra wants to know why the house was shunned by the locals and abandoned for nearly a century, despite commanding the best views in the county. Terhune digs deep into the mansion’s past and find more than one unsolved—and disturbing—mystery, dating back hundreds of years. When tragedy later strikes the eccentric Salvaterra family in their new home, Terhune must determine if the cause is the Gothic House-on-the Hill itself, or whether a sinister human plot is afoot.
