The Last Collar - Frank Zafiro - Bog

The demons that drive John "Mocha" Moccia to obsess, to put absolutely everyone under a microscope, and scratch away at every last clue, make him the best hardnosed detective in Brooklyn homicide. But these same demons may very well write the final chapter in his career.
He isn't the kind of detective to take no for an answer, but in his most recent case answers are damn hard to come by. Partnered with the conscientious Detective Matt Winslow, Mocha endeavors to solve the murder of the wealthy and beautiful Jessica Shannon, a woman who had every reason to live.
As Mocha and Winslow strive to push forward the hands of time and solve the murder, their imposing lieutenant breathes down their necks, suspects are scarce, and all of the evidence seems to be a dead end.
With the last precious grains of sand falling through the hourglass, Mocha pushes ever forward, determined to make an arrest, even if it means this collar will be his last.
