Gerard & Jacques (2000)

Blurb:
It’s a thrilling and romantic tale of an erotic novelist and his formerly aristocratic footman, set just before the French Revolution! Gerard frees Jacques from a high-class brothel in order to teach the boy how hard it is to make a living as a commoner, only to end up hiring him to be his footman. But when Jacques discovers that Gerard really does want a footman, not a live-in lover, a friendship--and possibly something more--begins to form between the two.
