The New Accelerator

by H. G. Wells

I sat down. “Give me the potion,” I said. “If the worst comes to the worst it will save having my hair cut, and that I think is one of the most hateful duties of a civilized man. How do you take the mixture?”

Murder in the Time World

by Malcolm Jameson

To hell with the law! For he had thought out the perfect crime. There could be no dangerous consequences. You can’t hang a man for murder with a body—a corpus delicti. For the first time in the history of crime, a murderer had at his disposal the sure means of ridding himself of his corpse.

The Man Who Walked Home

by James Tiptree, Jr.

Then that winter they came down for Christmas and John said they had something new. He was really excited. A temporal displacement, he called it; some kind of time effect.

Unsound Variations

by George R. R. Martin

Time is said to be the fourth dimension, but it differs from the other three in one conspicuous way—our consciousness moves along it. From past to present only, alas. Time itselfdoes not flow, no more than, say, width can flow. Our minds flicker from one instant of time to the next. This analogy was my starting point. I reasoned that if consciousness can move in one direction, it can move in the other direction as well. It took me fifty years to work out the details, however, and make what I call a flashback possible.
