In the deeply conservative Cotswolds, near Highgrove House, King Charles’ Country Estate, a hand-balancing drag queen contorts her body in front of an amazed, slightly stunned, audience. Waiters stand ready to deliver the evening’s second course, pumpkin-stuffed ravioli infused with squid ink. Normally, when one thinks about a circus, one can almost smell the hot dogs, peanuts, and cotton candy. Not here. Here, it smells of beef and toffee-apple pudding.
