A pretty funny book. The wife find that not only is her husband of many years having an affair, but the "other woman" looks like her only younger and firmer. Instead of the women fighting over the man, they devise a cleaver rouse to punish him. They swtich places!
This was printed in London. The edition published in the US was released under the name Switcheroo.
