Secrets of the Heart — Barbara Cartland

Zenobia and her father Lord Chadwell, have travelled all over the world, but when he dies, she finds that her stepmother has spent all of his money, and she intends to marry Zenobia to one of her own lovers.

Because Zenobia is fluent in the Eastern Languages, she found a post working to the Earl of Ockendon, who's seeking exhibits at the Colonial and Indian Exhibition to take place in the Royal Albert Hall in 1886. But Earl's sister warns her about him.
