Romantic Melisande Knowle, meeting the hero of her dreams, thinks he is her knight come to claim a lily maid. Alas! He is but Gervase Mallory, a stockbroker, on his way to a ball. She goes to bed, dreaming that he is rescuing her from dragons; he goes to spend the night not at the ball, but in an obstinate motorcar in a wood. Early in the morning Melisande wanders to the wood and meets her knight again. He promises to come for her that afternoon to carry her off. He comes, indeed - an ordinary man - once again Mr. Mallory of the Stock Exchange. Melisande suffers agonies, but Mallory shows that romance can exist even on the Exchange.
