4. Iron in the Fire

Complete story — includes the ending

Aayan is told that he is being expelled from his university for stealing medicine. With nowhere else to go, he accepts Carrie's offer. Carrie receives confirmation from Aayan that the man who threatened him was ISI operative Farhad Ghazi, the same man Quinn identified as having coordinated the attack that led to Sandy's death. Carrie and her team begin surveillance on Ghazi, but he escapes. Dennis Boyd, the ambassador's husband, is approached by ISI agent Tasneem Qureishi, who has learned that Dennis was Sandy's secret source of U.S. intel. She uses this to blackmail him into becoming her informant. Fara follows Aayan and discovers that Haqqani – his uncle – is alive, not having died in the airstrike, and is receiving deliveries of medicine from Aayan. Carrie realizes that she can use Aayan to get to Haqqani. She installs Aayan at a safehouse, claiming that they must wait several days for his passport and visa, a ploy which buys her time to interrogate him and earn his trust. As part of her recruiting strategy, Carrie seduces Aayan.
