Fractured

The people Saul Reardon had once helped, are dying.

Left at each murder scene are several cryptic puzzles, and obvious clues that Reardon is the true target. 
Questions mount.

Why Reardon and why his people? 

Is the doer someone from Reardon's gruesome past? Or someone from a more recent event? And does it include the sudden stalking of the woman he loves, Claudia Cabriati? 

With Claudia's help, and that of his loyal sidekick, Ethan Sloane and the mysterious Agency, who once trained him, Reardon must solve the puzzles and find the person responsible. 

Can he find the doer in time?
