Valerie Plame, left, and her husband, Joseph C. Wilson, sit in their convertible near the White house in this Nov. 18, 2003 photograph. Until three years ago, Joe and Valerie Wilson looked like another upscale couple in Washington, juggling serious jobs while keeping up with 2-year-old twins. He, a former ambassador turned international business consultant; she, an analyst for a Boston-based energy company - a working soccer mom. As it turns out, Valerie was a clandestine CIA agent and an expert weapons of mass destruction. The cast of characters in this latest tale of Washington intrigue _ the CIA leak investigation _ keeps growing as a federal prosecutor tries to sort out who told what to whom and whether any of it was a crime.
