I published an extensive review of this in Clues: a Journal of Detection. Obscure so I won't refer you to it. It was negative. Poorly written, poorly organized, strange preoccupations with Jews, Catholics and dragging in people who have nothing to do with the Ripper Murders. Crowley, for instance; he was eight at the time. Anyhow, unless you are an absolute Ripper collector who must have anything written on the murders, skip this one. There is actually nothing about black magic, so occultists need not collect this. ( )
