In Penelope Fitzgerald's book "Offshore," the concept of duty is portrayed as an obligation that often falls upon individuals when no one else is willing to step forward. This definition highlights the nature of responsibility and the personal sacrifices that come with leadership and commitment in challenging situations. Duty, in this context, becomes a defining characteristic of one’s character and moral integrity, especially in times of crisis.

Fitzgerald uses this idea to explore the lives of her characters who navigate their own challenges while illustrating that true commitment may require them to act when others refuse. The quote encapsulates the essence of her narrative focus, emphasizing the importance of taking action despite fear or reluctance, and underlining the notion that real duty often goes unnoticed until it is called upon.
