From The Perry Mason TV Show Book
In the farming community of Palmetto, gossip is a major form of recreation. Martin Walden's sister Frances uses this to break up his marriage. She pays Martin's nephew $1,000 to fake an affair with Andrea Walden. Martin, however, needs no encouragement to suspect his wife of adultery. He thinks she's been seeing an old flame, Nelson Tarr.

Martin and Tarr have bad blood and bad business between them, enough reason for the authorities to suspect one when the other is found dead.

Perry journeys to Palmetto to defend Tarr.
