The Horror from the Tombs — Florence Stevenson

A tranquil New England town is invaded by demon gods and a frenzied hate from beyond the grave.

Kitty Telefair, a young psychic member of a family of occultists and occasional guest star on a supernatural television talk show, is recruited by her aunt Penelope to decipher an ancient Egyptian papyrus. With a terse urgency, Penelope explains that she received a batch of artifacts from the tomb of Princess Khefra for her witchcraft museum, and that she
needs Kitty's expertise in reading the hieroglyphics. Against the wishes of her fiance, Colly (whose protests seem to end in implied sex scenes, the buttons ripped off Kitty's pant suit), Kitty agrees to help her aunt, but immediately experiences a sort of empathetic link with Princess Khefra.

Hearing screams as she arrives at her aunt's estate, Kitty discovers a local kindergarten teacher unresponsive in the passenger seat of a car -- apparently scared into shock -- with the driver missing. Kitty's aunt informs her that museum has been vandalized and the papyrus stolen. Aunt Penelope also introduces her to the estate's unexpected houseguests, Professor Gridley and his wife Beryl. Gridley, an anthropologist studying the museum's collection of occult objects, and his magnetically attractive young wife, cause Kitty to feel a strange -- yet instantly familiar -- sense of animosity, but she agrees to stay and help her aunt find the stolen artifact.
