In a Moonlit Garden — Cathy Maxwell

Posing as a tea merchant, Colonel Michael Sanson infiltrates an eccentric chemist's household in search of a stolen formula. But as soon as he lays eyes on the thief's niece, Lady Jocelyn, he is sidetracked into doing the fair lady's bidding. Little does Michael know that assisting in Jocelyn's scheme to make her former suitor jealous will send him into a tailspin of love and white-hot passion.
