Carver Weatherbee

Carver Weatherbee was about fifty, and he certainly didn’t look younger than that, though he did have the body of a younger man. He was built like a boxer — which was because he, in fact, was a boxer. Or had been thirty years ago, and he’d been a boxing coach for more than a decade, helping him keep his barrel-shaped box-like stack of muscles intact.
His face was worn and weathered now, wrinkles along his cheeks and his square jaw. His hair was mostly black and streaked with gray, but his unkempt goatee was mostly gray and streaked with black. He chewed on his lower lip almost constantly.
