Barnabas, Quentin and the Avenging Ghost (May 1970)

When the jury of which Roger Collins is chairman finds Harriet Barnes guilty of murder, she swears vengeance on the entire Collins family, then kills herself.

Soon, Celia Dalton, a guest at Collinwood, starts suffering strange spells. Each time she does, someone at Collinwood is violently attacked. Has Harriet Barnes taken over her spirit, making the innocent girl a bloodthirsty killer? Can Barnabas and Quentin save Celia—and the Collins family—from this menace out of the crypt?
