When Elaine Mercado and her first husband bought their home in Brooklyn, New York, in 1982, they had no idea that they and their young daughters were embarking on a thirteen year nightmare.

Within a few days of moving in, Elaine and her older daughter began to experience the sensation of being watched. Then came scratching noises and weird smells, followed by voices whispering, maniacal laughter, shadowy figures scurrying along baseboards, and small balls of light bouncing along the ceilings. From the beginning of the haunting, "suffocating dreams" were experienced by everyone except the younger daughter. These eventually accelerated to physical aggression directed at Elaine and both the girls.

This book is the true story of how one family tried to cope with living in a haunted house. It also describes how, with the help of a parapsychologist, Dr. Hans Holtzer, and the medium Marisa Anderson, the family discovered the tragic and heartbreaking secrets buried in the house at Grave's End.
