When wealthy industrialist and land owner John Mallathorpe passes away in an unfortunate accident without a known will, his estate falls into the hands of his wife and children. They live a lavish lifestyle until a humble bookseller uncovers Mallathorpes hidden will inside a book from the estate.

The bookseller, seeking legal advice, dies unexpectedly in a solicitors office. A keen-eyed clerk spots an opportunity to exploit this newfound knowledge for personal gain. Set in Edwardian England, this gripping detective story is filled with unexpected twists and turns.
