Baldacci, David. Amos Decker series

"When Amos Decker is called to South Florida to investigate a double homicide, the case appears straightforward: A federal judge and her bodyguard have been found dead, the judge's face sporting a blindfold with two eye holes crudely cut out, a clear sign that she'd made one too many enemies over her years on the bench. What at first seems cut and dry is anything but: Not only did the judge have more enemies than Decker can count--from violent gang members, drug dealers, and smugglers to a resentful ex-husband--but the bodyguard presents additional conundrums that muddy the waters even further. Who was the real target in this vicious attack? Meanwhile, Decker must contend with a series of unsettling changes, including a new partner--Special Agent Frederica "Freddie" White--nd a devastating event that brings Decker's own tragic past back to the present...and forces him to reckon with his future. As potential witnesses start disappearing, Decker and White are inexorably pulled down a twisted tunnel of secrets, crimes, and scandal--at the end of which lies Decker's deadliest threat yet"--
