Andre Norton: Stories

A Time Traders/Ross Murdock Story
If it is possible to conquer space, then perhaps it is also possible to conquer time. At least that was the theory American scientists were exploring in an effort to explain the new sources of knowledge the Russians possessed. Perhaps Russian scientists had discovered how to transport themselves back in time in order to learn long forgotten secrets of the past. That was why Ross Murdock, above average in intelligence, found himself on a hush-hush government project at a secret base in the Arctic.

The story is described as a "duel of the cosmic magicians." It involves two witch doctors who conjure up ghosts and demons against each other and might appear to be fantasy. But Norton bases the wizards' magic on the use of mildly hallucinogenic drugs, psychological manipulation and latent telepathy, which place the story within the realm of science fiction.
