The Doctor is feeling confident: this time the TARDIS has landed on Earth; in England; in 1963. But when he and his companions venture outside, they are soon lost in a maze of ravines and menaced by gigantic insects. And the insects are dying - every living thing is dying...

Meanwhile, in a cottage garden on a perfect summer's day, the man from the Ministry arrives to put a stop to the production of DN6, a pesticide with the power to destroy all life-forms. But the men who invented DN6 will stop at nothing - not even murder - in their desire to see DN6 succeed.

Can the one-inch-tall Doctor foil their plans?

Novelization of the Doctor Who TV series; three episode story "Planet of Giants" (1964), script by Louis Marks.
