Once More with Feeling — Phyllis A. Humphrey

When red-haired Jaime Campbell, a San Francisco stock broker, meets handsome Marshall MacRae, she finds there's more than business on his mind. She knows an involvement isn't wise, but her attraction to him makes her bend the rules a little. Then mysterious things begin to happen, some of which involve Marshall's two eccentric aunts, who are also Jaime's clients.

After a romantic weekend together, Jaime overhears a telephone conversation which seem to confirm her worst fears. Was Marshall investigating her instead of falling in love? Was he involved in illegal insider trading? Angry and frustrated, will Jamie's impulsiveness doom their love?
