question:  What is Lanfierre's profession?
context: He was strolling along a quiet residential avenue: small private houses, one after another, a place of little traffic and minimum distractions. But he was thinking about weather, which was an unusual subject to begin with for a person living in a domed city. In the ensuing contretemps they emptied his rear pants pockets, got his wristwatch and restored the contents of the handkerchief pocket. It was this rather than skill that enabled the police to maintain such a tight surveillance on him, a surveillance that went to the extent of getting his fingerprints off the postman's bag, and which photographed, X-rayed and chemically analyzed the contents of his pockets before returning them. Lanfierre's job was to ferret out aberration. Conformity had become more than a social force; it was a physical necessity. And, after years of working at it, Lanfierre had become an admirer of eccentricity. Lanfierre was almost proud of Humphrey Fownes. Lanfierre had held out on Fownes for months. MacBride and Lanfierre both leaned forward, as if waiting for the ghostly babble of voices to commence. The house could have been preparing to take off and sail down the.... MacBride looked at Lanfierre and Lanfierre looked at MacBride and then they both looked back at the dancing house. "I can't wait to see what he's got in there," Lanfierre murmured, watching the house with a consuming interest. Fownes stopped on the porch to brush the plaster of paris off his shoes. At least, he called it buffeting; he'd never thought to watch from outside. The downstairs closet was like a great watch case, a profusion of wheels surrounding the Master Mechanism, which was a miniature see-saw that went back and forth 365-1/4 times an hour. Or, as Fownes hoped it might appear, the illusion of the domed city vanished and was replaced by a more satisfactory, and, for his specific purpose, more functional, illusion. The sun and moon both looked down upon a garden that was itself scintillant, composed largely of neon roses.
