Billy Grade

Billy Grade turns up in Small Heath as a jobbing bookmaker, the kind of man who knows every fix and every price before anyone else does. He's affable on the surface, quick with a smile and a tip, and clearly hungry to move up from the betting pitches into the Shelbys' orbit.

Scanlan plays him with a salesman's charm that never quite settles into trustworthiness, so every deal he brokers feels like it could tip either way. The show uses him as a barometer for how far the family's business has drifted from horses and pitches into something colder, and he sells that shift without a wasted word.
