Against the backdrop of the 1893 World’s Fair, a young woman finds employment with an illustrious Chicago family—a family who may guard the secret of her sister’s disappearance. Sloane House is among the most gilded mansions of Gilded Age Chicago. Rosalind Perry, the new housemaid, pours the morning coffee before the hard gaze of her mistress. “It’s simple, Rosalind,” she says. “I am Veronica Sloane, heiress to one of the country’s greatest fortunes. You are simply one in a long line of unsuitable maids.” Back on the farm in Wisconsin, Rosalind’s plan had seemed logical: Move to Chicago. Get hired on at Sloane House. Discover what transpired while her sister worked as a maid there—and follow the clues to why she disappeared.
