When Grand Duke Sergei is murdered, Nicholas dismisses his police chief and considers Pyotr Rachkovsky as a suitable replacement even though he seems untrustworthy and is rumoured to use agent provocateurs. Both Sergei Witte and Empress Alexandra also have grave concerns about him and his methods but for different reasons. Nevertheless, with unrest fermenting and the memory of Bloody Sunday still fresh, he is appointed after seeking additional authority from the Tsar. Nicholas grants some concessions, including the creation of the Duma, as Rachkovsky begins using his forces in a deadly purge of troublemakers and revolutionaries in St Petersburg and beyond.
