I'm trying to find one person in London. I know that she had worked at the company, whose owner built a luxurious mansion near the art gallery, I think it was about Tate Modern, but I'm not sure.I would like to know if there is a house next to the gallery, like a private residence, and address. I would also like to know the suitability of any other art gallery. She said that the house is on the street, which can be called historic, but now it is no longer what it used to. It seems that Fleet Street is not suitable, but I do not remember exactly.
here you can find a whole list of London's galleries. Seems like a lot of work, but maybe you can contact some of the gallery owners (first of all at Tate Modern) to ask them if they know anything? Maybe they remember anything when they hear your friend's name?
In the near future everyone will have DNA tracking fluid injected in their spinal cord at birth so everyone can be located instantly whether alive or dead. And there will be a dropdown menu in the tracking software to identify everything they've touched in the course of their life.
