A thought to ponder.
If Mary Kelly was a prostitute as claimed on her behalf...
Then why, when Hutchinson saw her talking and walking with her next client..would she ask Hutchinson for money when she knew that the very person next to her would readily supply the dosh required?

The argument that "then she wouldn't have to do anything with the man" is weak. She was a prostitute..desperate for money. That comes first. And a tanner (sixpenny..6d) from Hutchinson would hardly have stopped her turning another trick....after all she is a desperate prostitute so far behind in her rent..she would need every shekel she could lay her hands on.

Something to think about?
