Nobody has ever been accurate about Marlowe Rooke.
She has been called clever, and difficult, and a waste, usually by somebody holding a clipboard. She has settled two hundred of the dead in the walls of Threadneedle for forty dollars an hour, cash, no certificate number. She is the best unlicensed bone-singer in the Fen and nobody has ever written that down.

It belongs to a professor who has not spoken aloud since 1846 - who returns her essays with four hundred words in the margins twice a week, in a hand that arrives in her head instead of her ears, and who is the first person in her life to be exactly, ruthlessly accurate about her mind.
