Foyle learns that the captain of the "Vorga" joined a cult on Mars and has had all her sensory nerves disabled, making her immune to conventional torture. Foyle kidnaps a telepath to interrogate the captain, and learns that the ship did not rescue him because it was picking up refugees, taking their belongings, and scuttling them into space. He also learns that Olivia Presteign was the person in charge. Olivia rescues him from Martian commandos, as she sees in Foyle someone who can match her hatred and need to destroy.
