Dear Grandson Carl,

I knew you would find a way to log into my webpage! Well done! I could not write too openly in my first letter… Who knows who might open the box…

There are people who would do everything to find me. So I have to be very careful. So extremely careful, that you still have to solve more of my riddles to open the other email. But I promise, it will be worth it!

I have to go, they are coming. I trust you will find me.
