That’s pretty damning evidence. If a publisher was on the fence they might pull her books quietly, but they wouldn’t make such a public attack without very good evidence that they thought would hold up in court. There was no equivocation at all.
The evidence, at least the evidence that I found cited as evidence, appears less damning.
Perhaps there is more damning evidence.
What I found was on the order of the degree of cross copying and similar themes, etc. found in many pools of young writers going back through literary history.
Rona Wang, whom I've never previously heard of, clearly used similar passages from her peers in a literary group and was called out for it after receiving awards.
I would raise two questions, A) was this a truly significant degree of actual plagarism, and 2) did any of her peers in this group use passages from any of Tona's work ?
On the third hand, Kate Bush was a remarkable singer / song writer / performer. Almost utterly unique and completely unlike any contempory.
That's ... highly unusual.
The majority of writers, performers, singers, et al. emerge from pools that differ from their prior generations, but pools none the less that are filled with similarity.
The arc of careers of those that rise from such origins is really the defining part of many creators.
It doesn’t prove anything, but it supports the theory that they have seen additional evidence.
After researching this a bit, it looks like someone from publisher says she admitted it to them. That certainly explains why they weren’t afraid to publicly condemn her.
Do you consider the announcement from her publisher that she admitted that she plagiarized passages as a damning response or damning evidence?
On the gripping hand
