This one is more a historical fiction with romantic tendencies; it's equal parts story-driven and character-driven. There's a goal to be met, but it can't be met without the characters. The romance is a backseat rider; it's there, but it doesn't really move the story forward. The story is set in Oxford University in 1951, where Ginevra “Gin” Bishop and Sidney Braithwaite are recruited by MI5 after an agent investigating a Soviet spy is poisoned.
Gin is an intelligent, wealthy Oxford student who works for a dying newspaper office. She's determined to prove that she is more than the "socialite" everyone who recognizes her name expects. Sidney comes from a working-class background and comes to Oxford carrying PTSD from being in World War II.
The author's writing is easy to read and refreshing in some aspects. The chemistry between the main characters and some of the side characters flows beautifully, and the snark is sharp. Her descriptions of the setting and events are detailed but not so much that it takes a page or 2 to describe a room. Her word choice is also ideal for the setting, not so childish as it feels out of place, but not so academic you don't know what's being said (not "yucky" but also not "organoleptically repugnant").
As is somewhat usual for historical fictions during this era, the FMC is comfortable challenging the rules set in place by society, what women can and can't do, who they can be with, etc. This is where Gin's character growth comes in; she has to figure out how to stand her ground without forcing the patriarchal hand that will throw her to the wolves to save face. This includes integrating into the very high society and the people therein that shed rather avoid. On the other side is Sidney, who appreciates being in the high society seats, but more so in the back. He likes the connections and the comfort since he's from a lower background, but doesn't like the limelight. Their partnership therefore develops both romantically and professionally.
Tropes
opposites attract
forced proximity
academic rivals/partners
espionage
murder mystery
Overall, I loved this story a lot (4.5/5) and feel that Westbury was able to bring a fresh look at the World War 2 London era without repeating the same concepts over and over again.
