The Heat Death of the planet from an overdose of global warming is not funny, nor is the occult, but the story has frequent elements of bizarre black humour as Gill and Steve investigate the interesting invention of Isaac Brainridge, designed to explore the future telepathically. This is the occult with a vengeance as Gill, Steve and Brainridge clash with his powerful but unscrupulous magician niece Athena. GillÕs sense of fun and quick wits save her (and Steve) but Brainridge and planet Earth may not be so lucky!
