3.5 stars. I'm still calibrating my Francis reviews.
Henry Grey is an earl's son, but in the sixties, all that means is that he has a manor home that's falling apart, a lot of assumption that he's stuck-up and useless, and a few good connections. At the start of the novel, Henry decides to start trying to live the life he wants. He quits his desk job and takes a much more physical one instead, overseeing the air transport of horses.
Henry is an unusual character and a little hard to warm up to at first. He admits himself that he's standoffish and doesn't give people much of a chance to get to know him or like him, partly--it emerges--because he reflexively assumes that if they did like him, it would only be because of his title, which is what he likes least about himself. He wants to be appreciated for his competence, and he is, in fact, highly but believably competent: he's a skilled amateur steeplechase jockey and a skilled amateur pilot, so you can see why he'd like this new job, even though the pay is terrible. It also explains why he spends so much time putting up with Billy, another hand on the job who does everything he can to make Henry's life difficult and painful: Billy hates Henry's position so much that Henry would only be giving him satisfaction by proving that he can't take his incessant awfulness.
It takes a little while for the plot to get going, but soon Henry clues in: there's something Yardman Transport is doing that isn't on the up-and-up. And there's the fact that his predecessors and coworkers keep going missing...
Tie in a little bit of romance, a frankly adorable international birth control smuggling ring, some immensely clever plotting, and one of the best action sequences I've ever read, and you have Flying Finish. It falters only in getting a little too hung up on some technical details and in the unavoidable, unfortunate fact that part of its plot has become history that no longer seems quite as shocking, but if that irks at all, there's always that incredible action sequence and a network of people passing on birth control for free to people who need it. Francis has a smooth style and pretty flawless plotting, and a sense of respect and sympathy for his characters that makes everyone involved feel human and striking. Once again, great fun.
