A secret society. A suspicious death. A trail of deadly clues.
London, 1889. When Emma Langley discovers a mysterious symbol in her late husband's diary, she uncovers a connection to a secretive treasure-hunting group with powerful members. Her investigation takes an unexpected turn when Lord Charles Harpole, a society member, is found dying in his hotel room.
The authorities rule it suicide, but Emma and her friend Penny Green aren't convinced. As they follow a trail of cryptic clues leading from St. Paul's Cathedral to Hampton Court, they find themselves caught in a deadly game.
With suspects ranging from the lord's grieving fiancée to his ambitious brother, Emma must solve the puzzle before the killer claims another victim. But in the fog-shrouded streets of Victorian London, someone will stop at nothing to keep the society's secrets buried…
Emma Langley returns in this gripping Victorian mystery that weaves historical detail with page-turning suspense.
