Miss Frances Baird, detective

Frances Baird is a detective with the Watkins Agency of New York City. She and a colleague are sent undercover to "The Maples" to guard a valuable set of diamonds during the festivities leading up to the marriage of Mr. Deneen's eldest son, James Jr. Within a few hours of their arrival, however, this seemingly simple task turns into something much more sinister, and it is ultimately left to Frances to unravel the truth of the matter.
