Carrie Wells (played by Poppy Montgomery) is not your typical New York cop. First she is a hottie and second she has hyperthymesia, which means she can remember everything. And I mean everything. What time the sun rose on a certain date, what day and where Al (played by Dylan Walsh) bought a shaving kit and most importantly for her job an entire crime scene. Her powers of recall and memory are incredible. For her they are a blessing and a curse. A blessing in that it along with her elevated deductive ability helps her solve tough cases. A curse because sometimes she just wants a memory to fade. The only case in which her memory has not been perfect is the one time she wanted to use it. When they were young Carrie’s sister Rachel was murdered. Carrie was around but cannot remember anything. It has been twenty-five years and the case remains unsolved.
