Overview

This episode introduces the extraordinary story of Václav Jelinek, a Czechoslovak intelligence officer who assumed the identity of Erwin van Halen, a Dutch boy given up for adoption during WWII. Beginning with his mother Johanna's traumatic wartime experience and continuing through Jelinek's espionage training and deployment to London, the episode reveals how Cold War spy agencies weaponized stolen identities and the human cost of such deception.

A Mother's Impossible Choice

In war-torn Holland during 1943-1944, nineteen-year-old Johanna van Halen becomes pregnant after being assaulted by a Polish soldier serving in the German army. Despite her father's collaboration with the Nazis, he rejects her and the child. After giving birth to Erwin in August 1944, Johanna struggles alone through a collapsing Europe before making the heartbreaking decision to leave her infant son at a Czechoslovak orphanage, eventually signing adoption papers in 1947 under family pressure.

  • Johanna van Halen, 19, was assaulted by Polish soldier Gregor Kulik at a dance in Nazi-occupied Holland
  • She gave birth to Erwin on August 24, 1944 in Amsterdam during Allied bombing raids
  • Her father, a Nazi collaborator, rejected her and refused to let her return home with the child
  • Johanna traveled east on a hospital train through the collapsing Third Reich to Czechoslovakia
  • She left Erwin at an orphanage in Rumburg in November 1944 when he was three months old
  • In 1947, social workers forced her to sign adoption papers, with her father insisting she had no other choice
" It doesn't matter that he was conceived in violence, or that the baby's father has returned to the front with no promise to return, or even that her own father has cast her out because of him. He is her child and she will protect him with her life no matter what happens. "
" This was never his home, and it never will be. Now sign. "

The STB Weaponizes a Stolen Identity

Years after Erwin's adoption, Czechoslovakia's communist secret police, the STB, systematically combed through orphanage records searching for identities that could be repurposed for espionage. In 1949, an intelligence officer discovered Erwin van Halen's file—a Dutch child with deceased parents and no remaining family connections. The STB recognized this as the perfect cover story: a ready-made life with authentic documentation that could be assigned to one of their agents for deep-cover operations in the West.

  • By April 1949, Czechoslovakia was under communist rule with secret police building files on the dead, displaced and forgotten
  • STB officers identified Erwin van Halen's record: Dutch mother, Polish father deceased, placed in care 1944, adopted 1951 with name changed
  • The file included birth certificate, nationality documentation, and adoption consent—everything needed to assume the identity
  • In the Cold War, such identities were considered weapons, providing authentic cover stories for intelligence operations
" These are children whose names no longer belong to anyone. "
