Danger

Not feeling great, I have done two covid tests, today and yesterday, both were negative, maybe I am just tired. 
The phrase deep excavations suggests to me something like a mineshaft not resurfacing a supermarket car park, but what would I know.  Meanwhile, literally in the background, the police were out in force at a nearby sports centre arresting a young man and escorting him to the back of a police van.  I might find out from the local paper or facebook what that was all about.
