From The Grey House:
Vincent watched as she ran to the edge of the roof, looked over the edge and ran a little to the left. She was right above the entrance. Natalia was over the edge before his men even ran out to the roof. Rebecca, in wolf form, reached the edge first. She sniffed the area and turned back as Anthony reached the edge. Joseph, he knew, would have gone for the street. Vincent pulled the window shut and latched it. Turning from the window, he pulled out his cell and called Mierka, who was waiting downstairs by the door.
“Don’t let anyone follow too closely; I want everyone back here in five minutes.”
