Palm Beach, Fla., invokes images of wealth, sun and beauty, but on Feb. 7, 2003 a sinister side of this town exposed itself when Linda Fishman, a beloved socialite known for her kindness, generosity and outgoing personality - who spent a lot of time there - was found murdered in her nearby home. After working for years as the chief court administrator in Hartford, Conn., where she met her husband Judge Milton Fishman, Linda moved to Boca Raton when he died unexpectedly of heart failure. Determined to make a fresh start Linda inserted herself in to the Palm Beach social scene, where the vivacious socialite developed a reputation as a caregiver to everyone from her nephew to her hairdresser. It was this benevolence that police believed was the ultimate cause of her death. But who would want Linda dead? At first, they suspected her nephew, Michael Jamrock, a popular DJ at local radio stations. With a shaky alibi and questionable financial situation compounded with his odd behavior in the wake of his aunt's death and a failed lie detector test, authorities had a powerful case. So powerful in fact that Michael's own family began to question his involvement too. As police dug deeper, however, they discovered that this socialite had a secret life - one filled with dubious younger men. But Linda's murder remained unsolved until investigators received a bombshell anonymous letter that would turn this case on its head.
