I left three notes around the flat for my girlfriend to find. They are "will", "you" and "me?".

That should keep her busy looking for a while, while i play PlayStation..
I gave mine clue which led to a deadly hornets nest...
To make her look longer you should send her on a scavenger hunt that promises cake i lost her for 2 weeks once with that trick. Set out a bear trap, lead her into the close and then gas her. She lived a good life, it was time. Boy that escalated quickly.
