When it came to the important things in life, including family, friends and a comfortable home, Janet March had it all. Then, suddenly, she was gone. In the early '90s, Arthur March became one of hundreds of American retirees who settled in the lakeside town of Ajijic, in central Mexico. At the time, his son, Perry, was a successful Nashville attorney in the prime of his career. But today, these two Americans, father and son, are using that Mexican paradise as a haven. "I brought Perry down here because he didn't have any other place to go," says Arthur Perry. In 1996, Perry March's wife mysteriously disappeared. Ever since, Perry says he's become a target, too, pursued by people he says are determined to destroy him. He says these same people are trying to kidnap his two children, Sammy, 12, and Tzipi, 8. "They're very concerned," says Perry. "We're taking a lot of extra security measures ... we have to deal with it every time we go out." To understand Perry March's life, you have to go back to his former life, back to Nashville and that summer night in 1996 when his wife, Janet Levine March, simply vanished.
