With cases from 1850 to 1997, these 32 examples span more than a century, across cultures, ethnicities, and socioeconomic status. But all were so beautiful, as James demonstrates, that they got away with murder.

When Madeline Smith, a Glasgow socialite, tried to end a relationship with one man to date another, her jilted lover proved difficult to shake. She solved the problem, James writes, with arsenic-laced chocolates. And in Warrenton, Virginia, mild-mannered heiress Susan Cummings gunned down her polo-playing husband, Roberto, following a disagreement. While these two women lived in different centuries and on different continents, both of their lawyers argued that they were too beautiful to be killers. And in both cases, the juries bought it.

In telling the stories of Madeline Smith and Susan Cummings—and 30 others—James proves the existence of the so-called Beauty Defense and shines a spotlight on how gender bias has actually benefited femmes fatales and affected legal systems across the world.
