The September sunsets were at their reddest the week the Professor decided to visit Aïn Tadouirt, which is in the warm country. He came down out of the high, flat region in the evening by bus, with two small overnight bags full of maps, sun lotions and medicines. Ten years ago he had been in the village for three days; long enough, however, to establish a fairly firm friendship with a café-keeper, who had written him several times during the first year after his visit, if never since. “Hassan Ramani,” the Professor said over and over, as the bus bumped downward through ever warmer layers of air. Now facing the flaming sky in the west, and now facing the sharp mountains, the car followed the dusty trail down the canyons into air which began to smell of other things besides the endless ozone of the heights: orange blossoms, pepper, sun-baked excrement, burning olive oil, rotten fruit. He closed his eyes happily and lived for an instant in a purely olfactory world. The distant past returned—what part of it, he could not decide.
