September 1916, they reunited at Mogilev, and spent time at Brasovo and Gatchina for the next six weeks, until Michael fell ill with stomach ulcers. They moved to the Crimea for Michael's recuperation. Christmas 1916 was spent at Brasovo as a family, where Natalia's daughter was "thrilled to the core" to hear that Dimitri had helped murder Rasputin, Tsarina Alexandra's self-styled spiritual mentor. Revolution After the February Revolution in 1917, Nicholas abdicated in Michael's favour, but Michael refused to accept the throne until ratified by the will of the people. By naming Michael as his successor, Nicholas effectively reversed the long-standing law that morganatically married dynasts forfeited rights of succession, but his actions were ultimately irrelevant. Power lay with the revolutionaries, not with the Tsar, whether it was Nicholas or Michael. Michael and his family were placed under house arrest in Gatchina. In September 1917, the house arrest was lifted. At the end of the following month the Prime Minister, Alexander Kerensky, was deposed in the October Revolution and the Bolsheviks seized power. With a permit to travel issued by Peter Polotsov, a former army colleague of Michael's who held a command in Saint Petersburg, the family planned to move to the greater safety of Finland. Valuables were packed and the children were moved to an estate south of Gatchina owned by Vladimir Dmitrievich Nabokov, the brother of one of Natalia's closest friends (Nadine Vonlyarlarskaya) and the father of the famous writer, Vladimir Vladimirovich Nabokov. The Bolsheviks discovered their plan, however, and their escape was blocked. The children returned to Gatchina, and they were once again under house arrest. Natalia managed to gain access to her safety deposit box, by claiming that she needed to examine some papers at the bank, and thus retrieved as much of her jewellery as she could conceal without arousing suspicion. The house arrest was lifted in November, but on 7 March 1918 Michael and Nicholas Johnson—who had been his secretary since December 1912—were re-arrested on the orders of Moisei Uritsky, the Head of the Petrograd secret police. They were imprisoned at Bolshevik headquarters in the Smolny Institute. Natalia visited Michael the next two days, 8 and 9 March 1918, with their friend Princess Putyatina. On 9 March, she barged her way into Lenin's office, which was in the same building, to remonstrate with him. In the evening, the Council of the People's Commissars decided
