The Consultant

This is an Apple Books audiobook narrated by a digital voice based on a human narrator.
Charles Deschamps, the Paris couturier, was going to bring down necklines in his next collection and one man knew about it six months ahead of time. Foreknowledge of a fact like that is all a good consultant needs to make him dream dreams and see visions: dreams of idleness and sybaritic luxury, and visions tinted uniformly green, like the folding money which alone can make such dreams come true. Even if it's not exactly ethical. Or legal.
