Seeking a challenge, Garrow agrees to defend two Spitalfield silk weavers who are charged with industrial sabotage, but one turns King's Evidence against the other. Southouse is diagnosed with typhus and faces an uncertain prognosis.
Garrow takes on the British colonial system when he prosecutes General Thomas Picton, accused of approving the torture of a girl while he was governor of Trinidad, but Lord Melville suggests a deal to help Lady Sarah get her son back.
Sarah runs away with her son, leaving Sir Arthur furious and Garrow distraught. Southouse's nephew George Pinnock distracts Garrow with the case of a man framed for murder during a polling day riot that may be part of a larger cover-up.
