Jill the Ripper?
Was the infamous serial killer Jack the Ripper actually a woman? That would explain why Jack was never found. Moreover, not many peple knew where the womb was located.
The name of the main female suspect is Mary Pearcey. She was a Londoner midwoman in her 20s and allegedly butchered and dismembered Phoebe Hogg, the woman her infidel lover had an affair with, and Tiggy, their toddling daughter. The motive was jealousy.
Until she was hanged she claimed to be innocent so Robin assumes that Jack the Ripper and James Berry, Ms Pearcey’s executioner, were one and the same person. “Maybe the Loch Ness Monster was innocent!”
