Kąkolewski was born in Suchedniów near Warsaw , nine years before invasion of Poland by Nazi Germany and the Soviet Union . His father was a lawyer , killed during the Siege of Warsaw in 1939 . Kąkolewski published his first novella at the age of 48 , after nearly three decades of often controversial ( from the communist standpoint ) , but highly popular non-fiction works about events in Poland 's postwar history . He interviewed former Nazi criminals living safely in Western Germany , e.g. Hans Fleischhacker , Heinz Reinefarth , subsequently described in his book '' Co u pana słychać ? '' published in 1975 , 1978 , and 1981 . His criminal novel based on authentic MO police records '' Zbrodniarz , który ukradł zbrodnię '' was filmed in 1969 , as one of the best Polish movies of the time , starring Zygmunt Hübner and Barbara Brylska . Kąkolewski wrote an entire book about the seminal postwar novel '' Ashes and Diamonds '' written by Jerzy Andrzejewski and filmed by Andrzej Wajda . He also wrote a monograph about Stalinist terror in the Kielce region , leading to Kielce pogrom of 1946 in postwar Poland
