The Right Hand of Evil - John Saul

When the Conways move into their ancestral home in Louisiana after the death of an estranged aunt, it is with the promise of a new beginning. But the house has a life of its own. Abandoned for the last forty years, surrounded by thick trees and a stifling sense of melancholy, the sprawling Victorian house seems to swallow up the sunlight. Deep within the cold cellar and etched into the very walls is a long, dark history of the Conway name--a grim bloodline poisoned by suicide, strange disappearances, voodoo rituals, and rumors of murder. But the family knows nothing of the soul-shattering secrets that snake through generations of their past. They do not know that terror awaits them. For with each generation of the Conways comes a hellish day of reckoning. . . .
