Query: jack the ripper 101

Very surprising after reading the her well-organized thrillers - this book is sloppy and you get the feeling she became increasingly disillusioned with her theory as she wrote it. She obviously knows very little about Jack and understands nothing about the artistic soul. After all, a gloomy artist like Sickert would have been fascinated by the case. She doesn't mention that he lived in rooms years after the murders and was told by the landlord that it had been lived in by the Ripper - of course he would paint it! Also, as for the man leaning over the woman in the painting in Ennui - everyone knew the Ripper was supposed to have approached his victims from the back and slit their throats. The only thing she has proved is that the mischievous letter writing Sickert probably wrote a couple of the 600 hoax letters - big deal!!
