Gregory Figg said this quote

she was like the merlin in pursuit of its airborne quarry, perhaps the snow bunting or a small meadow pipit; the avian prey is nimble but so is the predatory merlin with its inexhaustible stamina and unparalleled agility – round and round it chases the pipit, and the two flying at speeds almost impossible for the observer to follow.

The wiry man scratched his head, looked the two inquisitors up and down and cleared his throat softly. “We must be quick.” He turned to go, pulling his cloak over his head and shuffling through the door into the moonlight. The two inquisitors moved with impossible silence behind, floating across the straw-covered floor like the cats on the walls outside the hut. The cats froze at the disturbance before scurrying noiselessly into the shadows as the three silhouettes crossed the ten yards of grass before the blackness of the forest swallowed them. No fires flickered at this time, when the full moon was highest in the cloudless summer sky, and the three were the only waking souls in the hamlet.
