Aaron brings the money at the agreed place, the warehouse of the Goudveyls. An evangelisation campaign is going on outside, while Alex plays the piano inside. Vroom is murdered by a gunshot. Alex is witness of the murder, and is afraid he will be killed later because of that. As a student, Alex has sex with Yvonne, assistant of the professor, in an empty lecture room, at her initiative. At first Alex is willing, but when she wants more he walks away. On a second occasion, when he has Joanna Oberstein as girlfriend, he refuses sex with Yvonne. Now she threatens him with a knife. Then her boss enters the room and Alex can escape. Yvonne is fired. Alex's parents confess to Alex that in the war they could buy their business cheaply, because the owners were deported Jews. The parents say there is another important thing to tell, but they hesitate and do not tell it yet. Soon after this, Alex's parents die of carbon monoxide poisoning. It turns out that Alex's parents were not his biological parents. His biological mother died in the war, his biological father is Aaron Oberstein, the father of Alex's girlfriend. Thus Alex's girlfriend is his half-sister. Aaron did not know that Alex was his son. The Goudveyl couple was childless, and Alex was illegally supplied to them by Vroom for profit. The couple was blackmailed by Vroom regarding this. Therefore Alex's foster mother murdered Vroom. Since she is dead now, the case is closed.
