Myth-ion Improbable by Robert Lynn Asprin

Aahz said nothing. I think he was just glad she didn’t call him a Pervert, as so many did.

Suddenly, over the hill behind us, along the road, there was the sound of something coming. Glenda had us move back behind some rocks at the base of the cliff and watch. I made sure I had a pretty good view of the road so that I could disguise us all in the right clothes.

A minute later, two men appeared at the top of the rise. They were on horses and were headed slowly down the hill toward the town below. They both were dressed pretty much the same. They had on plaid shirts, jeans-like pants, high boots, and wide belts. Their skin was tan from a long time in the sun, and they wore wide-brimmed brown hats on their heads. One was a little older than the other and both had short hair and mustaches. They rode side-by-side in silence. After they got a distance down the hill, Tanda turned to me. “Get what they look like?”

“Easy,” I said.

Pulling in the energy I needed, I changed all of us into our local disguises. I gave us all black hats, and basically similar plaid shirts. Since I couldn’t see beyond the clothes what my magik did when I disguised someone, I glanced at Glenda. “How do we look?”

“Perfect,” she said. “Even Aahz’s tan is red instead of green.”

“Are we going to need horses?” I asked. “I can’t do them.”

“We might,” Glenda said, looking frustrated. “Especially if the golden cow isn’t close by. We might have to do some traveling, and, from what I remember, horses are the only means of travel here.”
