The labyrinth of death

London, 1895, and a widowed gentleman comes calling at 221B Baker Street. Due to his preoccupation with his grief at losing his wife, Fitzhugh Woolfson's daughter Hannah has become estranged from him, and has disappeared from the family home. Woolfson begs Sherlock Holmes to find her. Holmes and Watson soon discover that Hannah has joined a religious sect known as the Elysians - led by the charismatic Sir Philip Buchanan - which conducts secretive rituals in the countryside derived from Ancient Greek myth and religion. Hannah's friend Sophia has disappeared after becoming embroiled with the Elysians, and foul play is suspected. The companions must infiltrate the mysterious cult to discover the terrifying truth.
