Well, those Apricot Marmalade guys are at it again! In this sequel to Apricot Marmalade and the Edmondson Transmittal, Special Agents Reynolds, Bonner, Wilson, Dunn, and Cooper are once again matching wits with Soviet spies and other enemy agents in Vietnam-era Thailand. Ed Reynolds faces new challenges that keep him on his toes but seemingly just one step ahead of a court martial. Irv Bonner gets a new assignment in the northern part of the country that puts his life at risk but also gives him a chance at a meaningful romance. The team's biggest challenge in this go-around is to track down a physics graduate student who is intent on developing a nuclear device to threaten a major Thai city with extinction unless his demands are met. The agents are racing against the clock to stop tens of thousands of innocent people from being vaporized. Satire is alive and well in Apricot Marmalade and the Sangsuwan Equation.
