It must be a statement of the bleeding obvious to say that, of course, if the forgery was going to be in any way effective it required someone who was capable of disguising their handwriting and making it resemble, at least to some degree, nineteenth century handwriting. And, equally, if you didn’t know someone who could do it you couldn’t create a forged Diary. I have no idea why this would come as a surprise to anyone.
The point is that Anne has been identified by Mike as the person who did the forgery and none of us has the first clue as to whether she was capable of disguising her handwriting or not. That being so, what is there to discuss? And, consequently, what is the point of saying that the handwriting of the Diary doesn’t resemble Anne’s (or anyone else’s for that matter)? That, of course, is assuming it doesn't resemble Anne's handwriting and, as far as I am aware, the only sample ever seen by any handwriting expert was a sample taken for the specific purpose of testing (i.e. not her normal handwriting) and we don't even know what the expert said about it!!!!
Can we be certain Anne's handwriting doesn't resemble the handwriting in the Diary in any way? Have any examples of her normal unforced handwriting been produced?
