Robert hadn't revealed to anyone but Kate that he had that wretched rash himself. He had been taking concentrated doses of decongestants to keep working, and concentrated doses of potions to relieve the fever. And it made him look as though he was not affected, but the truth was that the only way to find out what worked and what did not without having a patient to test his potins on, he had t be willing to test them on himself. And, at this point, he didn't see that he was out much.
He had started a spell to keep names of the patients who had been in the hospital lately and was trying to sort them by degrees of illness to sort for patterns. The chalk constantly wrote by itself on the blackboard, writing names, addiing new names, and moving persons from list to list, back and forth, keeping them current for him. A separate list kept track of those who had died from the illness, and that list was growing. Every time a fatality entered his list, it made a crackling sound, as it if was being written on the wall in flame.
He picked up a parchment. "Would you do me a favor and send an owl with this to Angus or Kate? There are a few things I still need. I'd appreciate it."
