Martin's Press published his book, Beware the Night, co-written by Lisa Collier Cool, which chronicles his experiences as a demonologist and NYPD cop. Following his retirement, he began devoting himself to demonology cases full time.

He retired in 2004 as a decorated sergeant, having spent a portion of his time serving in the 46th Precinct in The Bronx, which has a reputation for being one of the most violent neighborhoods in all of New York City. The real Ralph Sarchie was a member of the New York City Police Department for approximately twenty years from the early 1980s through the 1990s. How long was Ralph Sarchie a member of the NYPD? It was these liberties that led to the movie posters being adorned with the phrase, 'Inspired by the actual accounts of an NYPD sergeant,' instead of, 'Based on the actual accounts of an NYPD sergeant.' This differs from director Scott Derrickson's previous exorcism movie, The Exorcism of Emily Rose, which follows the real account much more closely and was promoted with the 'based on a true story' tagline.

'He took liberties with certain aspects.' 'Scott took a lot of elements of my cases and put them in a different context than what I originally wrote about,' says Sarchie. In examining the Deliver Us From Evil true story, we learned that the movie does not follow Ralph Sarchie's cases exactly, but is rather a fictional retelling of some of the cases he worked on.
