Carolyn Jenkins is a voracious consumer of film and television. She graduated from Long Island University with an MFA in Screenwriting and Producing where she learned the art of character, plot, and structure. The best teacher is absorbing media and she spends her time reading about different worlds from teen angst to the universe of Stephen King.

Thrillers may be an easy sell, but Scarpetta is another type of show altogether. The Prime Video series could be a run-of-the-mill mystery like any other, but the newest series on the platform has found a way to stand apart. After 29 novels, Patricia Cornwell’s classic character has finally made it to live-action. Nicole Kidman stars as Kay Scarpetta, the chief medical examiner who returns to the field after years away. Scarpetta isn’t just a crime procedural. It is a character-driven drama that happens to take place in the world of crime.

When Scarpetta returns as the medical examiner, she is confronted with the case that made her career 28 years previously. A new killing leads her to the conclusion that a serial killer is at work, and the murderer convicted almost three decades ago may have been the wrong person. Kay and her brother-in-law, Pete Marino (Bobby Cannavale), throw themselves into an investigation that leads to the shocking finale of the first season.

‘Scarpetta’ Season 1 Finale Even Surprised Patricia Cornwell

With 29 books to choose from, the first season of Scarpetta is ultimately an adaptation of two: Postmortem and Autopsy. However, even book readers couldn’t predict the finale of the series because it was different from what Patricia Cornwell had put on the page. In the final episode, Scarpetta learns that the serial killer wasn’t someone the authorities had missed the first time around, but a copycat.

It turns out that the new killer is August Ryan (David Hornsby), the officer who appears queasy at the crime scene in the first episode. The final episode concludes when Ryan breaks into Scarpetta’s home with the intent of killing her. He confesses to the crimes, admitting that after seeing what the original killer, Roy McCorckle, had done to his victims, he was inspired to do the same.

“The blood, her rawness -- it changed me,” he says before confessing to killing Gwen and Cami Ramada. Then, when pursuing Scarpetta through the house, the medical examiner surprises him with a baseball bat and bludgeons him to death. Even after falling down the stairs from the blows, Scarpetta continues to strike him when it is clear he is already dead. This brutality is interrupted by someone opening the door to the grisly scene in a surprising cliffhanger. The episode ends without showing who it is, and Scarpetta’s eyes widen in shock.

This ending differs from Cornwell’s conclusion of Autopsy, which reveals that the killer was the handyman. In a recent interview, the author praised the changes to her work, stating it was “better than what I did,” following up with "What [the creators have] done is so good. And the fans will get the bones and the DNA of my usual stories, but they're going to get a whole lot more."

More is exactly what fans are hoping for, especially after the shocking finale. The good news is that Scarpetta was already greenlit for two seasons, so it is only a matter of time before viewers get a resolution to the startling cliffhanger.
