Last week’s episode showed Carrie (Claire Danes) and her team conducting a thrown-together sting, targeting a woman ensnared in a money trail leading to the chemically induced death, by mysterious chem-warfare agent, of a general in custody for attempted treason. (Let’s set aside, for the moment, just how spookily prescient that chemical killing has proven.) What was so good about that episode was how the mission kept shifting as things kept going wrong — and how, at the end, Claire’s hidden cameras uncovered evidence of a different motive entirely.
