Author’s Note

To sleep: perchance to dream: ay, there’s the rub…

To sleep: perchance to sleepwalk: ay, there’s the rub…

With apologies to Shakespeare for paraphrasing him, the concept of writing a story about a person who is a chronic sleepwalker and may have committed crimes while in that condition intrigued me so much that it became a reality.

My gratitude to nurse Jane O’Rourke for her kindness in showing me through the Pascack Valley Hospital Sleep Disorders Center and explaining its services. I am also grateful to the magazines and Web sites that offer so much information about sleepwalking and particularly to the following authors of articles on the subject: Marion Howard; Rosalind Cartwright, Ph.D.; and Fumiko Konno.
