Summary: A rogue element in MI-6 is testing an MPB (Micro Pulse Bomb) which incinerates people but leaves equipment intact. Through old contacts Jack learns the identity of the designer. Rachel goes to a conference in São Paulo, Brazil (should be Rio de Janeiro, because the conference is at a Beach Hotel, and there's no beach in São Paulo) to bug the designer's laptop. Under the cover name "Bob Brown", Julian Sark is there to do the same thing. Both do so successfully, and after a few drinks go back to his room for sex. In Brazil, Jack witnesses an arms transaction of a much larger MPB; one that ends in an ambush. The team realizes that Sark was the leak. Rachel and Sydney hire him. Jack and his companion are taken prisoner and moved to Tunisia. Sark arranges to buy the prisoners but gets double-crossed and is handcuffed to the bomb. Rachel manages to disarm it at last. Includes the sentence "What's a little treason between old friends?"
