After you spoke with the lady, you probably sent her a message on the phone about the job at her house, right?
If so, this is the bug that should have been fixed in patch 2.19.7. Here's a suggestion: restart the game, skip to the moment of the police interrogation, and after that, you'll probably talk to an elderly lady and meet the character Juliana. Only after talking to Juliana should you open the phone and send the message to Norah.
