Driving Force is one of Dick Francis' many non-series titles, this one from the early 1990s. It's on sale right now at Kindle UK for £0.99. I've always liked the oddly enjoyable insights that one gets from many of Francis' books into various industries that are adjacent to horse racing. (And some that are not so closely related, e.g. Proof...) In Driving Force, the adjacent industry is the business of moving often-insanely-valuable horses around the UK and Europe, and I remember this one quite fondly.

Spoiler:

Ex-jockey Freddie Croft now runs a fleet of vehicles which transport racehorses across the British Isles and Europe. But when two of his drivers pick up a hitchhiker who ends up dead, Freddie's got a big problem.

First, it quickly becomes apparent that the hitcher wasn't quite what he seemed.

And second, Freddie finds that his horse boxes might just be being used for moving something a lot less legal than horses.

Now he must figure out what is going on before the police, and before whoever is doing it cottons on and tries to stop him - permanently . . .
