The Eyewitness

Rachel Cartwright has a terrifying condition. Every 48 hours, her eyes shut tight - and stay that way for two long days. She can't work, can't go out. And, worse, when the world goes dark, she's certain someone is watching her. She can't prove it - but I believe her. And, as her doctor, I owe it to Rachel to help. I may not understand what's happening to her, but I've made it my job to protect her. To keep watch when she can't. But I can't help but feel there's something Rachel's not telling me. A shadow in her past she won't talk about. And now - I'm starting to feel it too. Like someone's watching me.
