You had a stalker. He never did anything to harm you, it was just creepy. Since there was no threat the police couldn't do anything.

One day you were out shopping. You had a a pair shoes you loved, when you asked the price it was out of your budget. As you went to put the shoes back your phone buzzed.

500,000 had been transferred to your bank account with a note that read:

"Is this enough, my darling?"
