Don’t be alarmed if you find a stray finger around town next week. It’s all part of a campaign to spread the word about Paul Gertner’s upcoming Piccolo show Ten Fingers, A Play of Magic. Twenty-five fingers will be hidden around Charleston and Mt. Pleasant starting June 1, and you can find clues on Twitter @tenfingersmagic. If you find a finger, that means you’ve won a ticket to Gertner’s magic show, which will be at the Village Playhouse June 4-11. If you find any other body parts, you may want to call the police.
