The novel returns to the opening chapter in the present day, revealing Ben on this date which takes place in the Cayman Islands. Their conversation about sleep disorders and Anna O makes Ben leave early.

Ben returns home and calls Clara and Kitty. He isolated himself to protect them after the spiral of Anna O’s case and his arrest. Reporters have bothered Kitty at school and Clara at work, but it’s lessened. Ben feels guilty for his family’s stress and like he has failed as a father. He talks to Kitty, then texts her, but she doesn’t respond.

The fallout of Anna’s case lasted for five months. Some suspect Harriet was behind everything, even the murders, and framed Anna using scopolamine. Others think she was Anna’s accomplice. Theories abound, but no one knows Patient X’s identity. Movies and book deals about Anna’s life are forthcoming.

Because harassment at Kitty’s school became too intense, Clara told Ben to leave the area for their safety. He moved to teach at Grand Cayman University. Since Anna went free and Ben is condemned, he searches for the truth.
