Real Crime Thriller Here Now?

Here I sat peacefully at my PC when a strange noise turned up some minutes ago.
Too near to be a helicopter.

But... look!

It´s a police-helicopter (you can click to enlarge, it says "Polizei"). It was hovering with open doors right above our living-room-window for minutes.
And it kept coming back twice.

Ingo is still at work.
We are the only apartment with a balcony in this house - and we´re ground-level, too.

Did I mention I´m all alone?
Sitting right beside the balcony?

Guess what I bought today, too. This is getting kinda weird and spooky!

Three Crime-Thrillers that take place in Braunschweig - one as a story, the others are real (and two more books on this town).
One is called "Without a Trace".

Oh, boy.
What did they look for?!
The prison is 1,5 km from here.
Ummm... I don´t even have a baseball bat or something like that here.

Seriously... do you have something to defend yourself in your home?
Should we get something?
Would I manage to try and hit someone with one?
Can Ingo come home now????

The helicopter seems to be gone.
Hope that´s a good sign...

Yikes, I can hear the heli just yet again!

Addendum... Ingo saw/heard it over the train-station on the way home.
Let´s see if there´s something in the (local) news tomorrow...
