Darby Sabini

Darby Sabini rules London's racecourses and betting pitches with the ease of a man who has never been seriously challenged. When the Shelby family starts pushing into his territory, he treats them with amused contempt — provincial nobodies playing at a game he already owns, easily managed and easily dismissed.

Noah Taylor plays him without a raised voice, which makes him scarier than the men who shout. He's soft-spoken, faintly bored, always seated like a man who doesn't need to prove anything — until the show lets you see how wrong that complacency is, and how quickly quiet menace can curdle into something uglier.
