Character Analysis
Grey-Pelham is a former coworker of Bradley Pearson, and part of a group of men who apparently burst into flames if they ever use one another's first names. We don't know much about him other than that Bradley avoids his wife (we're not sure why), and he seems like a friendly bloke.
This guy is more of a name on the page than a fully realized character, and his presence in the novel is mainly just to prove that Bradley Pearson has met more than just seven or eight people throughout his entire life.
