Romance writer Liz Fielding has had a story stolen - see her blogpost here. Someone else has taken her work, changed a few details and is passing the result off as her own. That's despicable. The thief, as defence, said she'd downloaded the original story and put it in a folder, then thought it was her own work. Yeah, right. And just happened to change characters' names as well. The lamest excuse I've ever heard.
Unfortunately now that works can be downloaded to PCs, and uploaded and self-published as ebooks so easily, I predict we are going to see more and more of this kind of thing.

Updated 26/2/12 - more on the story here. This was not an isolated incident. The thief has stolen several other works as well. She has now admitted plagiarism and apologised. I'm not sure that's enough, though.
Updated 27/2/12 - the story was picked up by the Guardian Books Blog.
