"The Ghost That Never Died" by Elizabeth Sheldon involves us in the office intrigues at a popular women's magazine, where brilliant but timid Miriam is eventually replaced in her editor's position by her more underhanded friend, who she gave an initial position to, Evelyn. It's a tale of astral projection and psychic dominance and quite interesting for its milieu setting, if somewhat clunkily written in spots.
Arthur Woodward's "Lord Of The Talking Heads" has an old man relate to a museum custodian how he came into possession of a unique object. While in South America, he was tricked by a ruse involving a lost city of gold and press-ganged into service as the slave of a madman who led a tribe of Jibaro (Jivaros. presumably) in the jungle, seemingly through magic powers. But escape, and an act of revenge, only exacerbates the problem... It's an inherently racist story (the slavemaster, Big Smoke, speaks in a "black patois" that is as bad as you'd expect) in the usual "harum scarum" mode, only noteworthy for involving shrunken heads.
