In the third installment of the Caroline Case Mysteries, the newly married, beautiful, and independently wealthy Caroline Case Jones leaves Chicago and then New York for Europe on the luxury ship Isle de France in 1929. She and Hannibal, her enigmatic new husband, enter a war-scarred continent embroiled in social turmoil and political upheaval. Their reputations as efficient and effective sleuths have preceded them. As Caroline and Hannibal travel to and across France, they use forensic techniques and deductive reasoning to solve a variety of perplexing murders. Chief Inspecteur Soucet from the French Gendarmerie Nationale gives Caroline a new nickname: 'la Chatte dans la Fenêtre, ' which translates to 'The Cat in the Window.'
