When the Doctor and Mel arrive in the Space Trading Colony, Iceworld, the Doctor can feel that there is mischief afoot. And he and Mel don't have to wait long before they discover the culprit, for there in the Refreshment Bar they meet up with that old intergalactic rogue, Sabalom Glitz.

Glitz is hot on the trail of hidden treasure and the Doctor, keen to do some scientific research, decides to join him. Down into the Ice Passages they go — through the Ice Garden, past the Singing Trees, beyond the Lake of Oblivion — in search of the Dragon's Treasure.

But the Doctor and his companions don't know the true worth of this mythical hoard. Only Kane, the most feared man in Iceworld, knows the secret of the Dragonfire...

Novelization of the Doctor Who TV series; three episode story "Dragonfire" (1987), script by Ian Briggs.
