inside job:For the Connie Willis novella, seeInside Job (novel) The term inside job colloquially refers to a crime, usually larceny or embezzlement, committed by a person with a position of trust who is authorized to access a location or procedure with little or no supervision, e.g., a key employee or manager. The perpetrator can also be a former employee who still has specialized knowledge necessary to ensure the optimum result of committing the crime. (Wikipediaより)
