Throughout Treason
Sir Martin Angelis is poisoned by Kara Yusova, who is Adam Lawrence's ex-lover and a former Russian spy.

While Martin is in hospital, Adam goes to his house to get a file about Audrey Gratz, which he passes to Kara Yusova. When searching for files, Adam comes across a file about himself. CIA was suspicious that Adam had been compromised, due to his intel on the planned attack.

After Adam learns that the CIA was behind Ella's kidnapping, and that his wife, Maddy De Costa, is in contact with Dede Alexander, he moves out and takes his kids to Martin's house. He tells Martin's wife, Mary, that he and Maddy fought, so they needed a place to stay. While Mary is distracted playing piano with the kids, Kara sneaks around the basement searching for a file about Baku, as she needs to know who killed the 5 men who worked for her in Baku. She had promised these men safety, so she owed it to their families to tell them who had killed them.

When Martin returns home from the hospital, he confronts Adam regarding his relationship with Kara. He shows him a file, and tells Adam he will be going to jail.

Adam takes his children to a house, where they hide. They are joined by Maddy. While Maddy and Adam argue, a shooter watches them from outside. Callum, who is in bed, hears noises and goes outside. He is grabbed by Kara, who drags him inside, much to the surprise of the others. She reveals that Martin ordered a hit on him. Kara and Maddy run outside to create a distraction. Kara runs into the shooter's car, dodging the shooter's bullets. Just as the shooter aims his gun at Kara, Maddy shoots him from behind. They move his body out of the way, and leave the house.

A man calls Martin to inform him that the shooter is dead, and they believe Adam and Kara are working together. Martin calls Dede and arrange to meet up.

At the meeting, Dede explained that she and an ops team arrived in the UK after Martin's poisoning to investigate Adam, because they believe he's compromised and a threat to Western security. Martin tells Dede that Adam and Kara shot one of his officers. He asks Dede to eliminate Adam and Kara, and in exchange, he will give her the proof against Adam, so she can return home a hero. Dede agrees.
