Lin had stroked his arm, clearly grateful for his concern. But she would tell him nothing. She said she was working on a piece of which she was tentatively very proud. She had found a space that she could not and did not want to talk about, in which she was producing a large piece that he mustn’t ask her about. It was not as if she had disappeared from the world. Once a fortnight, perhaps, she was back in one of the Salacus Fields bars, laughing with her friends, if with a little less vigour than she had two months ago.

She teased Isaac about his anger at Lucky Gazid, who had vanished, with suspiciously good timing. Isaac had told Lin about his inadvertent sampling of dreamshit, and had raged around looking to punish Gazid. Isaac had described the extraordinary grub which seemed to thrive on the drug. Lin had not seen the creature, had not been back to Brock Marsh since that forlorn day the previous month, but even allowing for a degree of exaggeration on Isaac’s part, the creature sounded extraordinary.

Lin thought fondly of Isaac as she adeptly changed the subject. She asked him what nourishment he thought the caterpillar might gain from its peculiar food, and sat back as his face expanded with fascination and he would tell her enthusiastically that he did not know, but that these were a few of his ideas. She would ask him to try to explain to her about crisis energy, and whether he thought it would help Yagharek to fly, and he would talk animatedly, drawing her diagrams on slips of paper.

It was easy to work on him. Lin felt, sometimes, that Isaac knew he was being manipulated, that he felt guilty about the ease with which his worries for her were transformed. She sensed gratitude in his lurching changes of subject, along with contrition. He knew it was his role to be worried for her, given her melancholy, and he was, he truly was, but it was an effort, a duty, when most of his mind was crammed with crisis and grub food. She gave him permission not to worry, and he accepted it with thanks.

Lin wanted to displace Isaac’s concerns for her, for a time. She could not afford for him to be curious. The more he knew, the more she was in danger. She did not know what powers her employer might possess: she doubted he was capable of telepathy, but she was risking nothing. She wanted to finish her piece, to take the money and to get away from Bonetown.
