Goodman Grey

Goodman Grey is a male Naagloshii first introduced in Skin Game.

Description
"An unremarkable looking man. Late thirties, medium height, solid-seeming, as if he had more muscle to him than was readily apparent. His features were clean-cut, pleasant without being particularly handsome. He had a slightly dark complexion and the right bone structure to pass for a resident just about anywhere in the western hemisphere and in chunks of the rest of the world. His dark hair had a few threads of grey in it. One thing about him wasn't average-his eyes. They were kind of golden brown with flecks of bronze in them, but that wasn't the strange part. There was a sheen to them, almost like a trick of the light, a semi-metallic refraction from their surface, there for a second a then gone again. They weren't human eyes."

Skin Game
In Skin Game, Grey was hired by Harry Dresden to act as his spy during the heist. Dresden and Grey talked in code, and Grey would eventually show his true allegiance by fighting Nicodemus when Harry said "Game over." Up to that point, Grey had pretended to work with Nicodemus, do his bidding, pretended to not like Dresden, occasionally bickering with him, and acted as if the two of them had never met each other. Grey's price was for "Rent money", which turned out to be one dollar. At the end of the book, Harry was shocked to discover Grey's identity. Grey responded with "You can't choose your parents." Grey then went on about how Dresden didn't choose to be Margaret LeFay's son, as she had committed some acts in which Dresden would not be proud to know about.
