This memoir tells the story of the house at Tõnismägi 16, where difficult decisions were made for the Estonian people in the 1940s. At the beginning of the Soviet occupation, the Central Committee of the Estonian Communist Party (Estonian Communist Party) led by Karl Säre was located there, and immediately afterwards, during the German occupation, the Sonderkommando 1-a, subordinate to the Security Police and SD Einsatzgruppe A, was located there under the command of Martin Sandberger. The house retained its infamous reputation later on. After the war, the Republican Party School and the Party Archives were located there. In 1952, the Party School was replaced by the Party History Institute of the Estonian Communist Party Central Committee. This institution was later popularly called a "nest of worms". The book is a sequel to the author's previous works "The Golden Sixties" (2011) and "Ten Years in the White House" (2013).
