A Plague of Zombies [Diana Gabaldon]
Once again, it's Lord John to the rescue. I wasn't too sure about the whole zombie thing, but I should have known that Diana Gabaldon could manage to make it believable (I think of the b-horror movie zombies when I think zombies and not the done by drugs still alive but not really zombies in this). This one being set in Jamaica helped that a lot, but I don't think she would have made zombies the focus of this novella if it had been set in England.
It was nice to see Lord John again, even if it has been a while.
