Rose controlled the West family finances, Fred giving her his pay packets. The room Rose used for prostitution was known throughout the West household as "Rose's Room", and had several hidden peepholes allowing Fred—a longtime voyeur—to watch her entertain her clients. He also installed a baby monitor in the room, allowing him to listen from elsewhere in the house. The room included a private bar, and a red light outside the door warned when Rose was not to be disturbed. Rose carried the sole key to this room around her neck, and Fred installed a separate doorbell to the household which Rose's clients were instructed to ring whenever they visited the household. Much of the money earned from Rose's prostitution was spent on home improvements.
