“It was hopeless. She was flawless. She was a sunbeam. Mosca gave up and got on with hating her.”

“Mosca and Saracen shared, if not a friendship, at least the solidarity of the generally despised. Mosca assumed that Saracen had his reasons for his persecution of terriers and his possessive love of the malthouse roof. In turn, when Mosca had interrupted Saracen’s self-important nightly patrol and scooped him up, Saracen had assumed that she too had her reasons.”

“Again Mosca felt she was up in the rafters, watching the mice. Little mouse, witless with fear. Running the wrong way. And here she was, just watching. Becoming a part of it by doing nothing.”

“Mosca had preferred it when she could hear the edge in her companion’s voice. Now she felt like someone who knows that there is a scorpion somewhere in the room but can’t see where it is.”

“Mosca had been so busy working the oars of her little plan that she had failed to see the iceberg upon which it was doomed to founder. And now here it was in front of her, a towering glacial mountain of selfishness, and she could not understand how she could have missed it. How vast was it? How far beneath the surface did it go?”

“She had told Erstwhile too much in the past, and thus he knew that occasionally she did go crazy. Sometimes it was when she felt particularly trapped or hopeless, or when the tunnels were unusually dark or stuffy, or when she got stuck in a crawl-through. Sometimes it happened for no obvious reason at all. She would feel a terrible panic tightening her chest and giving her heart a queasy lollop, she would be fighting for breath . . . and then she would be recovering somewhere, shuddering and sick, devastation around her and her fingernails broken from clawing at the rock walls and ceilings.”

“Irrationally, Mosca felt she should have inherited her father’s intimate knowledge of Mandelion. His throwaway comments about the city should have magically meshed in her mind, giving her a faultless instinct for finding her way around.”
