QUOTE : In Hamburg Griezman took a breath, and looked out at the evening gloom. Then he set to work. It was not taxing. It was merely a sequence of telephone calls. One number led to another. Like a neural pathway. An organization in action. Something to be proud of. The validation of a theory. As granular as he wanted. He could take it all the way back to the hapless trooper who took the original call. If he wished. Which he did. With fortunately simple questions. Names and addresses, of a person and a place.
