I Never Knew That About London Winn, Christopher, interesting Book.
Not a book expert bought this a few years ago now new. Has got slight foxing (believe that's what they call it).
Always meant to go out and see some of the places in the book but......
Some interesting facts from all parts of London.  Nice to browse through.
I even learnt that the explorer James Cook was a local to Mile End in its posh days perhaps? 
If you have any questions please don't hesitate to ask.
Thank you
