It's a reasonable question and one that feels almost impossible for Harold to answer. He has to wrestle his own vast opinions on John Reese into something palatable and able to be packaged for a stranger's consumption. Saying he's his proof that human beings can be good code is insensible and overly personal, even if it's the truest summary.

"Low-key and vaguely menacing," he says dryly, quoting himself from an old conversation. "To most people, that is. He's extremely competent, acquires weapons at a frightening rate, and can disappear into a crowd better than I can."

That last one is obviously complimentary, coming from Harold. But then he softens palpably and finishes with: "He's also a good man."
