It was whispered in society that Rasputin had seduced not only the Tsarina but also the four grand duchesses. Rasputin had released ardent letters written to him by the Tsarina and the four grand duchesses. The letters circulated throughout society, fueling the rumors. Pornographic cartoons also circulated that depicted Rasputin having sexual relations with the empress, with her four daughters and Anna Vyrubova nude in the background. Nicholas ordered Rasputin to leave St. Petersburg for a time, much to Alexandra's displeasure, and Rasputin went on a pilgrimage to Palestine. Despite the scandal, the imperial family's association with Rasputin continued until Rasputin was murdered on 17 December 1916. "Our Friend is so contented with our girlies, says they have gone through heavy 'courses' for their age and their souls have much developed," Alexandra wrote to Nicholas on 6 December 1916. In his memoirs, A. A. Mordvinov reported that the four grand duchesses appeared "cold and visibly terribly upset" by Rasputin's death and sat "huddled up closely together" on a sofa in one of their bedrooms on the night they received the news. Mordvinov reported that the young women were in a gloomy mood and seemed to sense the political upheaval that was about to be unleashed. Rasputin was buried with an icon signed on its reverse side by Maria, her sisters, and mother. Maria attended Rasputin's funeral on 21 December 1916 and her family planned to build a church over his grave site.
