Who is Martin from London Transports and what is their importance? London_Transports English & Literature Martin | London Transports

Frankie's boss at the BBC, Martin encourages her to "live and breathe the programme constantly" (p. 153), thinking up new ideas to make it great. After her first day at work, Frankie invites her friend, the unnamed narrator, to the BBC Club for drinks in order herself to run into Martin and get to know him. Frankie has heard that Martin's wife, a senior producer at the BBC, is a monster who keeps close tabs on him; her plan is to befriend the wife and convince her (despite her clothing) that she is no threat. The wife proves to be quite friendly. She lectures the narrator about remaining in teaching if she does not feel called to that vocation, and is reluctant to leave at 7 PM. As she does, the narrator realizes that she is her principal's sister.
