Doctor Who and the Green Death (The Doctor Who Library, 29)

The Green Death begins slowly. In a small Welsh mining village, a man emerges from the disused colliery covered in a green fungus. Minutes later, he is dead. UNIT, Jo Grant and Doctor Who in tow, arrive on the scene to investigate, but stangely reluctant to assist their inquiries is Dr. Stevens, director of the local refinery Panorama Chemicals. Are they in time to destroy the mysterious power that threatens them all—before the whole village, and even the world, is wiped out by a deadly swarm of green maggots?
