There had been some real presumption in a man of twenty-seven putting himself forward as a teacher of medicine at an age when many were just beginning their studies. Indeed, two of his pupils that first year had been older than he was. He wondered if they'd known it.

After a certain point, though, didn't your practice and your teaching speak for themselves? In Kerakek, here on the edge of the southern deserts, Rustem was respected and even revered by the villagers, and he had been summoned often to the fortress to deal with injuries and ailments among the soldiers, to the anger and chagrin of a succession of military doctors. Students who wrote to him and then came this far for his teaching-some of them even Sarantine Jad-worshippers, crossing the border from Amoria-were unlikely to turn around and go away when they discovered that Rustem of Kerakek was no ancient sage but a young husband and father who happened to have a gift for medicine and to have read and travelled more widely than most.

Perhaps. Students, or potential students, could be unpredictable in various ways, and the income Rustem made from teaching was necessary for a man with two wives now and two children-especially with both women wanting another baby in the crowded house. Few of the villagers of Kerakek were able to pay proper physician's fees, and there was another practitioner-for whom Rustem had an only marginally disguised contempt-in the town to divide what meagre income was to be gleaned here. On the whole, it might be best not to disturb what seemed to be succeeding. If streaks of grey in his beard reassured even one or two possible pupils or military officials up in the castle (where they did tend to pay), then using the dye was worth it, he supposed.

Rustem looked out the window again. The sky was darker now beyond his small herb garden. If a real storm came, the distraction and loss of light would undermine his lessons and make afternoon surgery difficult. He cleared his throat. The four students, used to the routine, put down their writing implements and looked up. Rustem nodded and the one nearest the outer door crossed to open it and admit the first patient from the covered portico where they had been waiting.
