Dennis Boyd is the husband of the United States ambassador Martha Boyd and also worked as a professor.


Dennis Boyd was eventually detained due to his questionable dealings with Pakistan's ISI. he also cooperated with Sandy Bachman's questionable dealing with ISI. After ISI elements kill Bachman, the organization blackmails Boyd.

He breaks into Carrie Mathison's home and switches her medication for her bipolar disorder which leads to her having a breakdown.

He was implicated in the security breach, leading to ISI's discovery of the embassy's secret tunnel complex, a breach that directly led to Haissam Haqqani's successful terrorist attack on the embassy compound.

After the attack was thwarted, Boyd was detained by US marines and imprisoned in the embassy holding facility. Knowing that he would be tried for treason and most likely executed, he asked Martha for her belt. She reluctantly handed it over. It is implied he decided not to kill himself, as he is among the people that are being evacuated to the States.


  • Boyd's reasons for illegally dealing with ISI are never explained, although he is seen lamenting over his sinking career as a professor and a drunk. He also resented Martha Boyd for being more successful than he was.
