A gripping, easy to read edition, rewritten in accessible clear, modern English

A dense yellow fog swirls in the streets of London as Sherlock Holmes and Dr. Watson accompany a beautiful young woman to a sinister assignation. Since her father vanished, Mary Marston has received a perfect large pearl one a year for the last six years and now a mystery letter telling her she is a wronged woman. Sherlock uncovers a tale of treachery and human greed that ranges from penal settlements on the Andaman Islands to the opium-fueled violence of Agra Fort during the Indian mutiny."
