Time Change By Karen Hamilton Rice What if there was a portable machine, no larger than a laptop computer, with which we could view history? What would that reveal to us? What would that reveal about us? What if you could key in a date and change time? This story begins in a Washington D.C. hospital. A ghost is noticed by employees of the MRI lab when the machine is in operation. Through trial and error they discover their spirit to be nothing more than an image created by two diverse technologies. They discover they can replay history. They realize they can build a machine to view history. When they begin, the inventors think of grand solutions, such as, viewing the building of Stonehenge or the Pyramids but the invention becomes popular for viewing personal history. It is a way to see grandma's wedding or mother's prom. However, there is a serial killer on the loose in the metro area. The detective assigned to the case decides the machine can also solve crime. The machine reveals the killer's last crime and the case is solved.
