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

Margaret's brother-in-law, who has never approved of her and who is suspicious of how she and Harry can afford to decorate their home so beautifully, Martin is married to a loud, lazy, sluttish, chain-smoking (and unnamed) woman whom Margaret likes to avoid. Thankfully, they visit just twice a year. Years earlier, when Harry gets a coworker at the factory pregnant, Martin had not been helpful and still chides him about younger women.
