The White Loop

He says he is from City Hall.

When someone knocks on Tessa and Hilde Brunes apartment door, they find an unusually short man dressed in white standing outside. Dark sunglasses.

White gloves.
An ID card he shows them only briefly.
He claims he is from Dortmunds public order office.

It is about their dogs, he says. An inspection. Just routine. But the man knows things he should not.

Tessas first name.

The name of one of her dogs. Details about their apartment and their daily lives.

Tessa refuses to let him in.

Soon, one thing becomes clear the man was never sent by City Hall. Then something happens in Dortmund that turns Tessas suspicion into a very real threat. The same signs begin appearing behind different apartment doors.

White gloves.
An alleged official visit.
People who live alone or who are easy to underestimate.

And again and again, the white loop. Someone is not choosing his victims at random. He watches. He tests. He waits for the moment a door opens.

Tessa knows what it is like to be underestimated. This time, that may be exactly what gives her an advantage.

Because while everyone else is still searching for a pattern, she is already understood the truth:

He is not inspecting apartments.
He is controlling people.
