Patrick McNulty was born in Port Colborne, Ontario, Canada. He married his high school sweetheart straight out of high school and then went on to university where he studied Neuroscience. After finding that he would rather write about strange behaviours of the brain than study them he left Ontario for British Columbia where he studied screenwriting and ended up working with the production company called the Zanuck Co.on an original screenplay he wrote called Dark Season. In the end Dark Season was not filmed so McNulty turned that screenplay into his first novel, Sleepers Awake. After leaving British Columbia, McNulty joined the Canadian Armed Forces where he was trained as a medical technician and was stationed in Petawawa, Ontario. Currently he is a police officer in Ontario living with his high school sweetheart, their three beautiful children and their dog.
