We are staying near the British Library and the St. Pancras Renaissance Hotel, left. So high our list will be an exploration of the newly restored Victorian hotel and a bit of time in the BL, though I'm afraid I won't have time to renew my Reader's Card this year.

It looks like a brilliant exhibition.
Now all I need is a few spurts of superhuman energy! We leave soon and I will report back in late July...
