One of the editors, Simone Marijnissen, explains that they have received a letter from, again, Joachim Stiller, asking them not to criticize Groenevelt.
He writes another letter to Marijnissen, and Groenevelt finds a 16th-century book, written by a German theologian from Augsburg called Joachim Stiller.
A graphologist determines that Stiller's handwriting is exactly what he would expect from a man "who doesn't exist at all, but could nonetheless write".
An American soldier was mortally wounded in the attack, and suddenly Groenevelt remembers the GI's name: Major Joachim Stiller, Longwood, Massachusetts.
At half past nine, a man comes out of the station, whom Groenevelt recognises as the American soldier from his youth.
Keldermans's connection with Joachim Stiller is also revealed: his daughter has died in the same attack that Groenevelt has witnessed.
