You follow Harpens voice but when you get to the point of where you hear it you can't see Harpen in the spot their voice is coming from. Harpen is yelling to someone to stop yelling and the voice continuously moves in a specific direction suddenly as though they were startled. You can then hear the voice calling for you, you can deduct that Harpen also can't see you.

With your shortsword? If so roll to attack.
