I picked up a stack of Dick Francis in a used bookstore on my trip in May, and I read them all back to back.
As the last time I did this, I'll sort them from most to least enjoyable. (Based mostly on Vibes, tbh.)
Longshot - Every writer of thriller and mystery presumably has one country house mystery in them, and this is a country house mystery, Dick Francis style. The protagonist is a down-on-his-luck writer ghostwriting a memoir of a famous horse trainer, who is evicted from his literal freezing garret just in time to move in with the subject of the biography in his big old country-house stable/manor - and walks right into the aftermath of a murder trial.
I hugely enjoyed it; the only thing that stops it from being one of my small number of all-time favorites Francises is some uneasiness surrounding the actual resolution to the murder. But it kept me guessing throughout; I really enjoyed how unpredictable the plot and characters were, had no idea who did it, and I also really enjoyed that the plot picks up not merely after the murder, but after the trial, and hero has absolutely NO interest in solving a murder - he's here to write a book! He just keeps finding clues and/or stumbling into the middle of someone else's coverup shenanigans. He also has a really unusual skill set - his usual area is writing wilderness survival guides, which gives him a vast array of hypothetical survival knowledge that obviously comes into play at the various points in the plot.
I loved everything about this book except the last couple of chapters. They didn't ruin the book for me, but it was a lackluster ending to a book I otherwise thoroughly loved.
Spoilers
When the killer was revealed, I didn't believe he could or WOULD have done what he did at the climax, which involves esoteric skill that's completely outside his skill set - basically he builds a bow and arrow and hunts the hero in the woods with it; it was a great scene, but even if he COULD do it, I don't think it would be how he'd choose to kill someone. This wasn't the thing that bothered me most, though, which was a generally uneasy tone surrounding the entire resolution. The hero decides to never tell anyone who actually did it for reasons I found somewhat hard to swallow (the killer commits suicide and the hero doesn't want to upset the guy's wife by letting her know that her husband killed or tried to kill multiple people! no!! I would have wanted to know!), and then to add insult to injury, there's a final few paragraphs that imply he never saw any of these people again, which really punctured the otherwise thoroughly enjoyable dramatic bonding under pressure in the book. Boo. But the rest of it was so good! Shattered - The protagonist is a glass sculptor who accidentally acquires a video tape that may contain the secret to a murder - except the tape is stolen before he even figures out there's anything special about it, which leads to several different groups of people trying to hunt him down and get it back. And it's not even the only tape full of mysterious secrets that's floating around! The hero isn't even sure which of the MULTIPLE mysterious video tapes is the one he had, or where any of them went; all he knows is that people are willing to kill him to get them back.
This is a strangely unmemorable book considering how much plot there is, and in fact I had trouble remembering enough plot details to write this up - it's sort of bog-standard Francis (horse racing, check; maguffin containing horse-related secret, check; unusual hero occupation; pretty love interest who is extremely interested in hearing all about the hero's unusual occupation, etc) but it was tense and fun and full of interesting secrets and details of of glass blowing, with a nicely developed mystery that really did keep me guessing and a tense finale. So: kinda basic Francis, but good basic Francis.
Edited to add: I think my most substantive complaint is that I would have liked the mystery to relate more closely to the hero's occupation, because it almost feels like it *should*, but it really doesn't; he could have done literally anything and it wouldn't have changed the plot. It kinda feels like an edit to bring all of the book's various strands together more tightly (the multiple video tapes, the hero's job, etc) would have taken it from good-but-unmemorable to really stellar. But it was fun.
Rat Race - I felt like I should have liked this book more than I did. It's got pilots, it's got a lonely hero who won't admit he's lonely and gets adopted by his love interest and her family ... and I sort of felt "meh" about it for reasons that I couldn't quite figure out. It felt like all the pieces were there for a book I should really enjoy but then I just kind of didn't like it as much as I did the above two, even though I liked the characters. It does have some excellent airplane sabotage and a really nice midair rescue scene in which the pilot hero has to talk a less experienced pilot in another plane with malfunctioning equipment through an emergency landing that was exciting and clever, and it has some nice character interaction.
I'm pretty sure some of my lackluster reaction to this book is because it turned out I've read it before and forgot, so kept getting vague flashes of memory, just enough to spoil a lot of the plot. I want to reread this book at some point when I haven't just read a pile of other Francis and see if I like it better.
Risk - My least favorite of an otherwise fairly strong bunch, and the only one I really didn't like. This book has a killer opening (the hero wakes up with a headache, tied up in the dark) and a really engaging first couple of chapters, and then goes straight off a cliff when he manages to rescue himself from his kidnappers (in a really thrilling escape scene) and then goes right back to his everyday life as a tax accountant.
Thing one: not even Dick Francis can make tax accountancy interesting, and we hear a lot about it. Thing two: KNOWING that someone is trying to kidnap him, the hero proceeds to make endless stupid decisions that more than once made me put the book down and simply stare at the wall. The book also contains a lot of philosophical musing from the hero on how high taxes naturally encourage even honest men to tax fraud, how overly high taxes have driven all the rich people out of Britain, and tax rates need to be lowered before the country goes to hell in a handbasket. I don't read Francis for the politics! Especially these politics! And finally, the thing I often enjoy about many of Francis's books is the way he handles ensembles (either isolated heroes learning to connect with people, or those who already have a handful of people they're extremely loyal to) and this just doesn't really have either of those; the hero does develop a couple of love interests, but is frustratingly disconnected from everyone around him.
