Agent Sayer Altair

In a residential Washington, D.C., neighborhood, a young woman's body is found in the basement of an abandoned house - starved to death in a cage, along with the video footage of a dark and deadly ritual. The victim is identified as the daughter of a prominent D.C. politician, and it falls to the FBI to track down the unconscionable psychopath who murdered her. FBI special agent Sayer Altair would rather conduct research on criminality than catch actual criminals. But when she's offered a promotion hinging on her next assignment, she reluctantly accepts the "Cage Killer" case.

Senior Special Agent Sayer Altair studies the minds of psychopaths. But even she didn't expect to uncover a killer within the Federal Bureau of Investigation. Rooting him out and exposing internal corruption got her a bullet wound and six months of desk duty. Now, she’s finally back in the field, called in when an off-duty FBI agent and his cadaver dog fall into a sinkhole filled with human bones.

After grieving the death of her fiancé and almost losing her job, Agent Sayer Altair is finally starting to rebuild her life. Her research into the minds of psychopaths is breaking new ground, and her strange little family is thriving. But Sayer’s newfound happiness is threatened when she is called in to investigate a girl’s body left inside a circle of animal figurines below a cryptic message written in blood. When they discover that the dead girl is one of 24 missing high school students, Sayer quickly realizes that nothing in this case is what it seems.
