Georgette Heyer: Not a fan of plagiarism.

From The Bookseller:

But it was Cartland's historical and linguistic errors that really offended the writer‚ herself a stickler for accuracy. "She displays an abysmal ignorance of her period. Cheek by jowl with some piece of what I should call special knowledge (all of which I can point out in my books), one finds an anachronism so blatant as to show clearly that Miss Cartland knows rather less about the period than the average schoolgirl," said Heyer, who told her agent she would "rather by far that a common thief broke in and stole all the silver".
