At least one Fed anyway.  He's a former FBI agent who spent 13 months as a Marine in Vietnam before returning to the U.S. and joining the Bureau in 1972. Noah Boyd (a pseudonym) will be my guest this afternoon at 4:30 on KSEN. Boyd retired from the FBI in 1993 and began writing fulltime. When he's not writing, he works on "cold cases". His latest tome is "Agent X" and I'll be giving away a hardback copy following today's interview. Last time I talked with Boyd, his stunning debut novel, The Bricklayer, had just been published and I'm more than anxious to catch up with this "G Man" to get "the story behind the story".
