Okay, so 'Night Train' gets thrown around for a few different books, but if we’re talking about the iconic 1997 Martin Amis one, the character list is famously spare, almost claustrophobic. It’s basically a trio. The narrator is Detective Mike Hoolihan, a female police officer with a brutal past and a cynical, worn-down view of the world. She’s investigating the apparent suicide of Jennifer Rockwell, the golden girl, a brilliant astrophysicist who seemingly had everything. Jennifer’s father, Colonel Tom Rockwell, is the third key figure; he’s Hoolihan’s boss and a father figure to her, which makes the whole investigation unbearably personal.
The novel hinges on the dissonance between how these three people see the world. Hoolihan deals in the messy, violent facts of life and death, while Jennifer was exploring the vast, cold equations of the cosmos. The Colonel represents a kind of ordered authority that completely fails to explain his daughter’s fate. There are other names that float through—Jennifer’s boyfriend, some colleagues—but they’re shadows. The real conflict is inside Hoolihan’s head as she tries to square Jennifer’s perfect life with her violent end, and what that search does to her own crumbling sense of reality. I finished it feeling like I’d been staring into a black hole with her.
