#1 New York Times bestselling author Stephanie Laurens pulls back the curtain on a world that has been hidden from us . . . until now.

Montague has devoted his life to managing the wealth of London's elite, but at a huge cost: a family of his own. Then the enticing Miss Violet Matcham seeks his help, and in the puzzle she presents him, he finds an intriguing new challenge professionally . . . and personally.

Violet, devoted lady-companion to the aging Lady Halstead, turns to Montague to reassure her ladyship that her affairs are in order. But the famous Montague is not at all what she'd expected--this man is compelling, decisive, supportive, and strong--everything Violet needs in a champion, a position to which Montague rapidly lays claim.

But then Lady Halstead is murdered and Violet and Montague, aided by Barnaby Adair, Inspector Stokes, Penelope, and Griselda, race to expose a cunning and cold-blooded killer who stalks closer and closer. Will Montague and Violet learn the shocking truth too late to seize their chance at enduring love?
