The Algebra of Ice
A genius maths nerd, a weird webzine publisher, and the Doctor’s old ally, the Brigadier, find themselves helping the Doctor and Ace solve what should be a simple puzzle: the appearance of a crop circle in the Kentish countryside.
Hardly uncommon. But there are some peculiar features. It’s not a circle but a series of square-sided shapes. It’s filled with ice. And it draws the Doctor and Ace into a confrontation with a reality right next to zero.
- The Algebra of Ice was the sixty-eighth BBC Past Doctor Adventures novel. It featured the Seventh Doctor, Ace and Alistair Gordon Lethbridge-Stewart. This is the first Past Doctor Adventures novel to feature this line up of Doctor, companion and Lethbridge-Stewart.
