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

A native of the British West Indies, Wilma laughingly calls her white roommate Sandy Ring a cousin. Wilma is studying for a university degree while working odd hours in admissions. Good-looking Nelson says that Wilma is a communist; Wilma claims that she would scarcely be earning a degree if she wished to overthrow the system and says that Nelson should attend to Margaret, the hard-working mother of his three children, rather than flirting and gossiping.
