Last night, our final night in the UK, we went on a Jack the Ripper tour. You meet at Tower Hill tube station at 7.30 pm on any night of the year barring Christmas Eve and Christmas Day. You don’t have to book. You just turn up. It costs £9, and it goes for about an hour and a half. The lady who took us through the streets of Whitechapel was very knowledgeable about the murders of the five women that took place in 1888. She showed the group of about 30 where the murders occurred, and gave plenty of insights into the characters and local circumstances of people living in the east end when Jack the Ripper struck. Jack was never caught, and no solid evidence exists to confirm Jack’s identity. But more than 100 theories abound.
