Any Stories Told from the Perspective of a Head Eunuch or Head Palace Maid?

I've read so many palace-intrigue novels. Whenever there's a big event, the unassuming chief eunuch or senior palace maid on the sidelines may seem unimportant, but they can make a real difference. I'd love to read palace-intrigue novels from their perspective, hahaha. No CP is fine too.
