After all this time, Anna Gregson is still learning the ins and outs of the FBI...even the secrets of the building and who is really inside. She knows that Captain Walsh is Harboring The Renegade, who was once her Guardian, but she didn't think she'd ever work with him again. When the "All-Powerful" case returns and agents go missing, she questions who in her past would want to hurt them all. When the Protector and her Partner get captured, Anna knows she needs to team up with the Guardian and a Genius before A Chance At Concealment is lost.
