Anita Margolis, young, beautiful, carefree, has vanished into thin air. She left her home to attend a party one wet evening, but has not been seen since. She is reported missing soon after by her brother, whom she shared a flat with, the acclaimed but eccentric artist Rupert Margolis. Inspector Burden quickly forms an impression of a wanton young girl simply gone off somewhere with a boyfriend having neglected to let anyone know. After all, she was that sort of woman, in Burden's opinion. However, Wexford has his doubts, and those doubts will soon be confirmed, and they will soon find themselves enmeshed in a case that will throw every assumption they make into doubt.
