What Remains: Evidence and Method in Paranormal Investigation challenges the two failures that have long defined paranormal investigation: belief without discipline, and evidence without method. Drawing on decades of field experience, a background in psychology, years in law, and experience overseeing scientific research programs, William A. Smith offers a practical framework for investigating unexplained claims with rigor, fairness, and intellectual honesty. From witness interviews and case intake to contamination control, chain of custody, environmental baselines, audio review, logical reasoning, and ethical reporting, this book replaces hype and performance with real investigative standards. This is not a debunking manual. It is not a believer’s handbook. It is a guide for those willing to do the work carefully enough to earn the right to say that something still does not add up. Ideal for paranormal investigators, skeptics, researchers, journalists, and curious readers interested in how extraordinary claims should actually be examined.
