So I found Patricia Cornwell's Portrait of a Killer: Jack the Ripper Case Closed. It's her investigation into the Ripper case and her convincing exposition of the facts and why they led her to the conclusion that the painter, Walter Sickert, was in fact Jack.
I thought I'd have a look at more of Walt's paintings so I went online and found some. They are all over the place. He really is well-known and respected as a painter. I noticed, too, that he had started a painter group in England that included the painter Harold Gilman. Gilman is my stepmother's father. I found this quite interesting. My stepmother Elizabeth had mentioned that he was no small shakes as a painter but I had not actually heard of him before I met her. Now I see that there are Harold Gilman galleries.
The Ripper book is good. She did a lot of work putting that together and it's working. She researched the times down to tiny details, found what she could on Sickert's life (including operations he had as a child on his penis - suggesting that he was horribly mutilated in that area, which further suggests a partial motive for later murdering women). I think this would not be considered "heavy" reading but neither is it really "light". Maybe I need to go out and find something yet another layer lighter.
