Where and when did these murders occur? I'm curious, because the Ripper murders were so unprecedented and awful that I would think that any similar crimes would have set off alarm bells if they occurred anywhere in Britain.

I haven't seen the 60 minutes segment for some time, so I don't exactly recall. She was quite specific about the particular murders she considered candidates, in England and France (though none in London). Sickert was in the vicinity in each case. She even believes one of his more famous paintings was inspired by the scene of one of these later murders. You'll have to dig up the old 60 minutes tape, or see her book for more detail. It's quite interesting.
