The stay-at-home wife of a very rich husband drives a pink sports car, is into everybody's business, and is rumored to be having an affair with a local teenager. When her husband finds the pool house ablaze with two bodies inside, and the cops' theory of a love-triangle murder falls apart, they turn to Gregor Demarkian for help.
