THE HOLZER FILES 10 p.m. on Travel Channel. Hans Holzer was a prolific ghost hunter. By the time of his death, in 2009, he had written well over 100 books on paranormal subjects, the product of international travels and troves of research. Holzer sought out subjects who believed they had experienced paranormal phenomena. This series, produced with the involvement of one of Holzer’s daughters, looks back at some of his work . It centers on a paranormal investigator, a medium and a researcher, who revisit some of the cases Holzer once looked into. First up: a historic (and possibly haunted) house in Rye, N.Y.
