Ghost Hunter: The Groundbreaking Classic of Paranormal Investigation
Hans Holzer
Tarcher Penguin
Trade Paperback

From the publisher's website:

The prestige edition of the classic, trail-blazing work on ghost hunting will intrigue new fans and longtime devotees alike—part of the new Tarcher Supernatural Library.
 
Fifty years before Paranormal State, Ghost Hunters, and Most Haunted, there was Hans Holzer—a man known as the “Father of the Paranormal.” Holzer pioneered ghost-hunting methods still used today, and brought ghosts and ghost hunting into popular culture in the second half of the twentieth century.
Ghost Hunter presented some of the first-ever case studies of haunting investigations, taken from Holzer’s own practice in the New York City area—ranging from Civil War-era spirits to the tormented ghosts of murder victims.

For devoted ghost-hunting aficionados curious about the practice’s history, there is no better place to start than the first book Hans Holzer wrote, Ghost Hunter.This is the 1963 book that launched his publishing career and gained him international fame.

The first three titles released in Tarcher's Supernatural Library are Ghost Hunter (by Hans Holzer), Romance of Sorcery (by Sax Rohmer) and Isis in America (by Henry Steel Olcott).
