Showing Face Down Upon an Herbal by Kathy Lynn Emerson

Susanna, Lady Appleton, is ordered by Queen Elizabeth to assist Eleanor Madderly with an herbal she is preparing. The queen’s emissary failed to mention that a man had been murdered at Madderly Castle—and that part of Susanna’s mission is to solve that crime. Traitorous forgery, hidden identities, and secret passages all make her task the more dangerous. 2nd of the Face Down historical mystery series by Kathy Lynn Emerson; originally published by St. Martin's Press and Kensington
