The pieces of evidence are handed over to the Criminology Museum (a group of crime-experts who are not criminals), just at that moment, a job applicant (the bearded Jarko Jansen) arrives.
Jarko solves his first case in cooperation with Officer Noordenwind by subjecting the victim to a lie-test, using the number of scratches in a vinyl record.
Without recognising her, he asks for the address of the building that Franka just came out of; she misleads him by sending him round the block, and returns to the shop where she hides in what appears to be a secret elevator.
Back at work, the officer, Jarko, Franka and Professor Factotum exchange recent experiences, and thanks to the latter, they learn that the offender is Argos Attak, a man who borrowed books about escape from deportation.
Once more, Argos explains that he stole the money and bought the plane to start a revolution to liberate Oceanaqua from the oppressor who recently gained power.
