Kate saw Cassidy fall. She suddenly thrust her bags into Brian's hands. He expected her to go help Cassidy but instead, Kate moved deliberately into a small crowd of people and seemed to disappear, heading in the direction of the man who had tripped Cassidy. He knew better. Kate's seers sense had gone off and she was trailing the man who had tripped her.
"I suggest we stay here for the moment and keep our eyes open," Brian told Cassidy. "Kate's on the trail of something, I think. Don't use your wand in these muggles unless you want to reveal our secret to the whole world--no matter what. Look around you. There are high security muggle cameras everywhere. For now, all we can do is wait."
Kate followed the man into a rather darkened cocktail bar in the mall. He just seemed to be gone. Then from behind her a massive hand snapped like lightning out of the shadows and grabbed her around the throat with, clearly, enough strength to break her neck with one bare hand. And he was doing a good job trying to strangle her as it was.
"I'll give you a sporting chance, Old Woman," the deep, dark voice said. "Its not you I want, but if you're fool enough to try me again, I will take you instead of your daughter. I wonder how your husband would like to lose his wife as a starter? Might be a nice touch, dont' you think?" Kate was losing air fast, and she could hear breaking sounds in her neck. She left her wand sheathed and merely reached behind her and cast a wandless, nonverbal sectumsempra. The blood spurted against her back. She felt it. She backed into the ladies room and transfigured her clothing into white slacks with and a floral printed tunic with a high mandarin collar, completely hiding the massive marks around her throat. She transfigured her shoes into little white sandals and used a glamour spell to hide any lingering traces of trouble. Then she returned to Cassidy and Brian.
"We were seen," she told them. "He was here. He's gone now. He apparated out. I suggest we get home."
