Difficulties range from Jane's apathy to being placed on the marriage block, the determined efforts of Sheila's cousin, Mabel Claremont, to win wealthy David Fenner for her debutante daughter Clarissa, and Jane's attraction to David Parkson, an American drummer who plays in the orchestra at the coming-out balls.
