The prostitutes at Nell Gwynne’s house are carefully selected women of many talents. Few know that their clients include not just the upper crust of London society, but The Gentlemen’s Speculative Society, who pay mainly, not for pleasures of the flesh, but for secrets and spycraft. Their payments to the madam seem to include technology which really seems to have no place in 19th-century Britain. When the Society arranges a job where the women are hired as entertainers at a very private auction, a (literal) bedroom farce ensues.
