Roger and Kate Starte again give a personal inflection to this story of a second freelance mission -- this to Eastern Serbia and life behind the Iron Curtain. Asked to retrieve some incriminating records in a cave, and to photograph some rocket platforms, they proceed to Belgrade and, from the first, experience strict surveillance. With the help of a Doctor, they reach their objective to face the assault of a once cooperative, now crazed peasant. A happy-go-lucky American makes possible their return to Belgrade. This is a tense tour of a police state and evenly exciting entertainment. Those who enjoyed Dragoman Pass will especially want to read this.
