"Ten-agers" Greta and her cousin Derek are constant companions. Upon finding an old well, of course they must pry off the rotten wood cover. Derek fetches his Dad's fishing rod. He soon hooks a beautiful gold ring with a red stone setting, followed by an ornate piece of cloth. It becomes apparent that there is a body in the bottom of the well ... the police must be called in.

Greta immediately takes possession of the ring. She must possess that ring! Without knowing why, she turns the ring toward her palm to make it less noticeable. Curiously, she soon becomes haunted by a strange, terrifying feeling—that someone is following her. Someone like a shadow. She also starts hearing a whispered voice telling her to do bad things. Is this voice only in her head? Then comes the murder. Greta, nearby at the time, remembers nothing. But, she can't shake the nagging feeling that she is somehow responsible, even though she has been saying No, No, No to the whispers!
As the murder investigation proceeds, dark family histories are slowly revealed.

Death Stone has been described as "quietly eerie", "schizo creepy".
