Nightmare Fuel / H. G. Wells

• A story called The Cone, which is about a steel works manager whose hired artist is having an affair with his wife. During a tour of the works, the manager throws the artist off of a catwalk onto the cone on top of a blast furnace. The story then goes on to describe, in the most gruesomely horrific detail imaginable, how the cone opens and the man is roasted to death.
• "The Country of the Blind" reverses the above example. The realization that they're better at tracking him blind than he is with both eyes; all he can do is watch. And, of course, why they're tracking him!
• "The Empire of the Ants", in which the intelligent ants decimate entire villages, seemingly unstoppable. It's all but said that they will eventually conquer the world.
• "The World Set Free" accurately describes nuclear weapons and their effects. In fact, it invented the concept of nuclear weapons.
