The Maid Episode 15

Upon placing the pearl on the left hand of the Buddha, the drawer underneath opens. This contains dolls which suppress reincarnation and was taken as proof by the Empress Dowager that Madame Su and her daughter killed Lin Ji Fu. But Madame Su had dirt on the Empress Dowager, so she let them off. Instead, she'll burn the building that includes the proof. When Xi Yan speaks up, guards are ordered to lock her up in the same building to be burned. (Source: Italophilia at kisskh)
