Faced with what seems like a bare wall, you could easily assume that any art on it has been and gone. Come a little closer, though, and you’ll find things aren’t quite as they appear. Three unsightly rawlplugs – which at first look like the evidence of something once present but hastily removed – actually contain delicate turquoise inlays, while the ‘forgotten’ screw is cast in 18-carat white gold and set with a sparkling white sapphire. Like any good magician, Susan Collis has a talent for misdirection and surprise, and her works reward anyone prepared to take a second look.
