Heinrich Walks In?

"You don't see what he's doing, do you?" Sarra asked.

I looked again at the wall of notes. It did seem a bit mad to cover an entire wall this way, but he wasn't mad, he was a mastermind. If the notes were world capitals and he had little drawings of missiles, or if even one of them had something to do with the machine, maybe I would buy it. But this looked more like a brainstorm map for a novel. Here he was worried about a new job, here he had a long trip and a fear of flights, here he had a brother who he looked up to but also worried about.

"How did you find out his address?" I asked.

"Keep looking," Sarra said. It was not like her to brush me off like this.

"Hey," I said, touching her shoulder. "I'm serious."

She shook me off and walked through the little bungalow again.

"Aha," she said suddenly, walking quickly to the rather cheesy framed painting of the Blue Mosque. She lifted up the picture and there was a safe beneath it. She leaned in and started spinning the dial like she was some kind of safe cracker. I couldn't help chuckling. Three clicks later it swung open. I stopped chuckling. She reached in and pulled out a notebook.

The front door opened and someone came into the house.
