sobered, nodded awkwardly, and acted like he wanted to speak, but didn’t. He turned to a laptop, gave it a command. The screens on the wall displayed what looked at first glance like a collage of images. At center was a photograph Acadia had recently taken of Alex Cross’s house from across Fifth Street. Dotted lines traveled from various windows in the house out to pictures of Dr. Alex, his wife, his grandmother, his daughter, and his younger son. Set off to one side was a framed picture of Damon, Alex Cross’s older son, seventeen and a student at a prep school in western Massachusetts. Digital lines went out from each portrait, linked to images of schools, police stations, churches, grocery stores, and various friends. There were also lines connecting each member of Cross’s family to calendar and clock icons. “He uses mind-mapping software and an Xbox 360 with Kinect to make it work,” Acadia explained. “It’s interactive, Marcus. Just stand in front of the camera and point to what you want.” Intrigued now, Sunday stepped in front of the screens and the Kinect camera. He pointed at the photograph of Cross. The screen instantly jumped to a virtual diary of the detective’s recent life, everything from photographs of Bree Stone, to his kids, to his white Chevy sedan and his best friend, John Sampson, and Sampson’s wife, Billie. Sunday pointed at the calendar, and the screens showed a chronological account of everything he had seen Cross do in the prior month.
