In honor of Agatha Christie's 100th birthday, mystery bookstore owner Annie Darling plans a week-long celebration of mystery, treasure hunts, title clues, and Christie trivia. The last thing Annie or her guests expect is that the scheduled fun and mayhem will include a real-life murder. Hart is the first author ever to win all three major mystery awards for her novels.
