Frank Cappelano used to hunt killers. Then he became better at being one.

From behind prison walls, Frank finally tells the story of how a respected FBI agent walked away from the Bureau, vanished into the backroads of America, and became Veritas. He writes for Neil Baggio, the protégé who caught him. Or maybe he writes to keep teaching him.

The journal begins with excuses. Then the excuses turn into bodies. Then the bodies become a purpose.

For readers of the Neil Baggio Suspense Series, Why I Kill is the missing shadow behind Veritas. For everyone else, it is a disturbing ride with a man who knows exactly how law enforcement thinks — because he used to be one of them. He knows the rules. That is why he knows how to break them.
