What is the Edinburgh Fringe? It’s a sabbatical, a pit stop, a pause-and-check-the-map opportunity for actors who don’t quite know where to go next. Alison Skilbeck has written a ‘serio-comic celebration’ of Shakespeare and her performance attracts a decent crowd for a show that starts at noon. She plays a fruity-voiced thesp, Artemis Turret, who delivers lectures about the Bard’s older females to groups of layabout pensioners gathered in a scout hut.
