The case begins with a shock, and the twists keep coming,
when FBI Agent Smoky Barrett and her team are called in by the Director himself to investigate a murder committed on a flight from Texas to Virginia.
It soon becomes clear that they are dealing with a serial killer who has already struck a truly horrific number of times. A killer who can find people with secrets - the deepest,darkest secrets we keep even from ourselves - and is using them to target and destroy his victims.
The case is about to go public, and when that happens, with all the accelerated power of the internet behind it, public hysteria is not far behind. Smoky is under the most intense pressure of her career to get results, yet the team has never been faced with such an apparently insoluble problem.
Who will the next victim be? Everyone in the world has secrets.
