In the months since working on their first murder involving the Optical Evidence Program, Detective Veronica Sloan and Special Agent Jeremy Sykes have been trying to solve the rest of the puzzling case. That becomes even more imperative when Veronica receives data from a test subject...who sends her the images of a brutal murder he committed.

It’s a race against time as the taunting clues come in. Ronnie and Sykes find themselves traveling across the country, always one step behind the killer who is zeroing in on his real target...in the nation’s capital. It will take all of Ronnie’s ingenuity and every bit of her courage to not only solve this crime, but the one that’s haunted her for months.

Especially because, this time, she’s the target of a killer’s brutal rage.
