Violent, tyrannic squatters leader Marco Kruisveen (27) is knife-butchered in Paul Mast's building trough throat, belly and both eyes. In his blood was written 'see no evil' on the wall. The answering machine recorded 'You've seen to much'. Fellow squatters Nicole Kemper, Marco's bitchy, pregnant ex-girlfriend, and severely dyslexic painter Tom Koopmans, who was covered in blood, her present lover, and blind sculptor Wanda Lammers, all lack alibis. Someone threatens and follows the detectives, even stabs Vledder in the arm.
