The Doctor and Peri visit the planet Targos Delta to check in on old friend Professor Albrecht Thompson, only to discover that he has vanished. He was last sighted taking a shuttle to the holiday resort of Paradise 5, then never seen again.
The Doctor’s curiosity is piqued. They must investigate, but they must do so stealthily... Peri will go undercover on Paradise 5, while the Doctor hides in the shadows. Because paradise holds a terrible secret beneath the white marble and golden trimmings. The mute Cherubs have a story to tell. And the Elohim are coming.
