Seven months after their last encounter, retired FBI agent Jack Kale and Atlanta Police Detective Beth Sturgis are reunited by a new case that pits them against the Sandman, a nearly perfect assassin who leaves no clues, can change his appearance seemingly at will, and has eluded police on four continents for years. It’s now a race against time to protect the Sandman's next targets --- two witnesses scheduled to testify before a grand jury by the end of the week. With the clock ticking down, Kale and Sturgis dive headfirst into a desperate chase to catch the killer before he strikes and disappears again.

After years of paying her dues on the force, Beth Sturgis has earned her place as a detective for the Robbery-Homicide division of the Atlanta PD. Now, she's heading up a major manhunt for a potential serial killer who’s working his way inward from the outskirts of the city. The copycat elements in the first crime scene lead Sturgis to retired FBI agent Jack Kale, who was responsible for apprehending and nearly killing the murderer known as the Scarecrow, the same Scarecrow who appears to be this new killer's terrible inspiration.
