Two days in London

We didn't check in to the George until about 8pm on Wednesday, so just the next two days to experience London after more than two decades.
On Thursday we explored the environs of Russell Square. First a sortie into the British Library. After filling out forms with more intrusive questions than for a Chinese visa in the days of Deng Xiao Ping, we got reader registration and I located a book I've been hunting for years.(joy!!) It would take 48 hours to fetch from off site, so sadly the request to read was abandoned.
Nearby the British Museum beckoned.
In the afternoon a walk to peek in Gray's Inn garden designed by Francis Bacon, followed up with a long stop in the pub opposite to imbibe a largish cider.
On our walk I saw a quintessential streetscape above the red buses.
