Logan and Wheeler investigate when Josh Lemle, a reporter friend who had backed Logan after he had gotten himself exiled years earlier, comes to Major Case to report his own murder. Logan agrees to help his friend find out who used Polonium-210 to poison him, but Lemle is reluctant to reveal the whole story to Logan because not all of it is pretty. Both Hazmat and the FBI get involved as the search turns city wide, with both the mayor and Homeland Security wanting answers.
