Geoffrey Dromgoole

Geoffrey Dromgoole moves in the polished orbit of arms dealer Richard Roper, one of the well-dressed men who keep Roper's business running smoothly and don't ask too many questions. He's clubbable, quick with a joke, comfortable with money and power — the sort of ally whose charm makes the rot around him easier to miss.

Tobias Menzies gives Dromgoole an easy, clipped confidence that never quite curdles into menace, which is precisely the point — he's dangerous because he's so socially fluent. The performance finds the specific pleasure of a man enjoying his own competence, letting the audience feel complicit before they notice what he's actually part of.
