Given name: Karol Family name: Szatensztajn

At the age of 19 he has a very high opinion of himself and is appointed Adler's assistant. He wanted to join the military academy but the war stopped him. He was too young to join the Jewish Police, thus, he becomes a messenger avoiding labour camp. Later Lejkin takes care of him and then he can give vent to his ambitions - he safeguards Lejkin's secret records.
