Solve an actual murder, that of a young woman found strangled in a park in France who may have connections leading to the highest levels of the British establishment. As they embark on their own investigation, the Queens of Crime discover that they’re stronger together. But soon the killer targets Dorothy Sayers herself, threatening to expose a dark secret in her past that she would do anything to keep hidden.

Rosalind knows if she just takes one more X-ray picture --- one more after thousands --- she can unlock the building blocks of life. Never again will she have to listen to her colleagues complain about her, especially Maurice Wilkins, who would rather conspire about genetics with James Watson and Francis Crick than work alongside her. Then it finally happens --- the double helix structure of DNA reveals itself to her with perfect clarity. But what unfolds next, Rosalind never could have predicted.

She is the daughter of Richard Greener, the first Black graduate of Harvard and a well-known advocate for equality. Belle’s complexion isn’t dark because of her alleged Portuguese heritage that lets her pass as white --- her complexion is dark because she is African American.

In December 1926, Agatha Christie goes missing. Investigators find her empty car on the edge of a deep, gloomy pond, the only clues some tire tracks nearby and a fur coat left in the car --- strange for a frigid night.

She had an idea that might help the country fight the Nazis...if anyone would listen to her.
