"i see. you know that, do you?"

i didn't answer that. i knew it was rhetorical. he stooped to retrieve my button and handed it back to me. "best sew that on good and tight, cadet." he put his notes on me into a folder and then sat down at his desk with a sigh. "you're going home in a couple of weeks, aren't you? for your sister's wedding?"

"for my brother's wedding, sir. yes, i am. i'll leave as soon as my tickets arrive. my father wrote to colonel rebin to ask that i be released for the occasion. the colonel told me that ordinarily he would strongly disapprove of a cadet taking a month off from studies to attend a wedding, but that given the condition of our classes at present, he thinks i can make up the work."

the doctor was nodding to my words. he pursed his mouth, seemed on the verge of saying something, hesitated, and then said, "i think it's for the best that you do go home for a time. traveling by ship?"

"part of the way. then i'll do the rest by horseback. i'll go more swiftly by road than on a vessel fighting the spring floods. i've my own horse in the academy stables. sirlofty didn't get much exercise over the winter. this journey will put both of us back into condition."

he smiled wearily as he settled into his desk chair. "well. let's pray that it does. you can go, nevare. but check back with me next week, if you're still here. don't make me remind you."

"yes, sir." i dared a question. "how is your research progressing?"

"slowly." he scowled. "i am at odds with my fellow physicians. most of them persist in looking for a cure. i tell them, we must find out what triggers the disease and prevent that. once the plague has struck, people begin to die quickly. preventing its spread will save more lives than trying to cure it once it has a foothold in the population." he sighed, and i knew his memories haunted him. he cleared his throat and went on, "i looked into what you suggested about dust. i simply cannot see it being the cause of the disease." he seemed to forget that i was merely a cadet and, leaning back in his chair, spoke to me as if i were a colleague. "you know that i believe the onset of the plague and the swiftness of its spread mean that sexual contact cannot be the sole method of contracting it. i still believe that the most virulent cases stem from sexual contact..."

he paused, offering me yet another opportunity to admit i'd had carnal knowledge of a speck. i remained silent. i hadn't, at least not physically. if cavalla soldiers could contract venereal disease from what we dreamed, none of us would live to graduate from the academy.

he finally continued, "your theory that something in the dust that the specks fling during their dust dance could be a trigger appealed to me. unfortunately, while i did my best to gather data from the sickened cadets before they became too ill to respond, the disease took many of them before they could be questioned. so we shall never know exactly how many of them may have witnessed a dust dance and breathed in dust. however, there are several flaws in your theory. the first is that at least one cadet, corporal rory hart, witnessed the dust dance and had absolutely no symptoms of plague. he's an unusual fellow; he also admitted to, er, more than casual contact with the specks themselves, with no ill effect. but even if we set rory aside as an individual with exceptionally robust health, there are still other problems with your theory. one is that the specks would be exposing themselves to the illness every time they danced the dance. you have told me you believed that the speck deliberately sowed this illness among us. would they do it at risk to themselves? i think not. and before you interrupt-" he held up a warning hand as i took breath to speak, "-keep in mind that this is not the first outbreak of speck plague that i've witnessed. as you might be pleased to know, the other outbreak i witnessed was close to the barrier mountains, and yes, the specks had performed a dust dance before the outbreak. but many of their own children were among those stricken that summer. i can scarcely believe that even primitive people would deliberately infect their own children with a deadly disease simply to exact revenge on us. of course, i suppose it's possible that the dust does spread the disease, but the specks are unaware of it. simple, natural peoples like the specks are often unaware that all diseases have a cause and hence are preventable."

"maybe they face the disease willingly. maybe they think that the disease is more like a, uh, like a magical culling. that the children who survive it are meant to go on, and that those who die go on to a different life."
