This short story by Burgess dates to the 60's and may have been first published in The Hudson Review, Spring 1968. It was collected in several anthologies thereafter. Here we have a future literary historian with the ability to travel through time and space and he goes back to check out Shakespeare. I won't pretend to understand the scientific gobbledygook tossed around here, I don't think one is supposed to. It's rather bad science fiction when it does it like that. Burgess is just using this as a device to get our near future fellow and his scientific machine and driver to deliver him to London, but time in this story isn't fixed, and when you go across space and time you will likely get some pushback and where you go is an alternate history time similar to ours but sometimes with big differences. This is entertaining in a mild sort of way, but a little too strange. like eyeballs on women's breasts strange. This might be the only science fiction short story Burgess wrote. That might be a blessing. ( )
