Mrs. Lakowski has suffered a nasty shock. As she was about to enter the 4th-floor apartment of Mr. Lauwerk, for whom she regularly cleans, two masked men lunged towards her. One of them knocked her brutally to the ground. As she fell, she managed to tear her attacker’s stocking mask from his face. Then the assault victim discovered to her horror that the two robbers had murdered Mr. Lauwerk.
Chief Inspector Derrick fears that Anna Lakowski’s life might be in danger as soon as the media reveal her name. But for the time being he is disappointed that the terrified murder witness isn’t able to give a description of the culprit – despite having seen his face.
