From a longtime reader of the blog:

   “I’ve been trying to track down the author and title of a book I read a couple of decades ago. It’s about…humanoid killer giant river otters. Set in South America, main character maybe an Anglo who gets a job running a plantation, probably by a British author, from the 1950s-1970s. Kind of a weird thriller. Does it ring a bell? It seems like a novel John Blackburn would have written, but it doesn’t seem to be in his bibliography.”
