We'd all agree that hospitals can be scary places - from superbugs to surgery suites. But, did you know that some of them may also be haunted? It makes sense, since hospitals are at the vortex between life and death, the place where people enter and leave this world. Today's guest, Richard Estep, is a well-respected paranormal investigator and author of several books based upon his research. His latest book is The World's Most Haunted Hospitals: True-Life Paranormal Encounters in Asylums, Hospitals and Institutions. With a lifelong curiosity about the paranormal, Estep trots the globe gathering chilling stories, like the ones he writes about in this book from tales told by nurses, doctors and patients about ghosts and spirits.
