She may have written about this stuff in the various diaries, including the old ones that she had kept. We don't know what was in them, but given she wrote that she was the most attractive female in the office, seated in the window for any man to see (which she did), it doesn't sound like she held a lot back. It also doesn't sound like they are necessarily reliable, because that bit was inaccurate. It's also possible there were so many names the police thought they'd no chance of tracing them all.
AS quoted from them a bit - mainly to give instances of her dyslexia - but all this told me was that when she wrote "Mr Kipper" in her desk diary, it's not at all clear that's what she meant to write. What actual name does someone with dyslexia mis-spell "Kipper"? One is reminded here of the dyslexic atheist who didn't believe in Dog.
Having a lot of blokes is like driving 100,000 miles a year. It shouldn't be dangerous, but unfortunately it is, in that it heightens the risk you encounter a nutcase. About 5% of people are psychopaths I think, so if you've been involved with 40 men, you've probably encountered about two of them. In fact, any woman may encounter many more, even if not that active. They can fake confident and charming, which means some unlucky women are attracted to them. They're mostly not murderers, but unlike the other 95% of men, there's a chance they are.
