Wallander had no plans for the day. It was a Tuesday and he was free. He had been putting in a lot of overtime, not least because of the frequent, large-scale Vietnam demonstrations both in Lund and Malmö. In Malmö there had been a clash with the police. Wallander had found the whole situation distasteful. He was not sure what he thought of the protestors' demands that the United States get out of Vietnam. He had tried to talk to Mona about it the day before but she had not had any opinion other than that 'the protestors are troublemakers'. When Wallander, despite everything, insisted on pointing out that it could hardly be right for the world's greatest military power to bomb a poor agricultural nation in Asia to devastation – or 'back to the Stone Age', as he had read that some high-ranking American military official had said – she had struck back and said that she certainly had no intention of marrying a communist.

That had knocked the wind out of his sails. They never continued the discussion. And he was going to marry Mona, he was sure of that. The girl with the light brown hair, the pointy nose and the slender chin. Who perhaps was not the most beautiful girl he had ever met. But who nonetheless was the one he wanted.

They had met the previous year. Before then, Wallander had been involved for more than a year with a girl named Helena who worked in a shipping office in the city. Suddenly one day she had simply told him that it was over, that she had found someone else. Wallander had at first been dumbstruck. Thereafter he had spent a whole weekend crying in his apartment. He had been insane with jealousy and had, after he had managed to stop his tears, gone down to the pub at the Central Station and had much too much to drink. Then he had gone home again and continued to cry. Now if he ever walked past the entrance to the pub he shivered. He was never going to set foot in there again.
