She knew that I knew nothing. She was not about to tell me anything. I decided to shoot in the dark. One thing was sure: if they knew anything, they knew more than I did. The dark was all I had to shoot in. But I knew now that something was not right with Jo-Jo. I thought about the most probable reason for Jo-Jo to run — that he had seen who mugged Stettin. In which case, someone else would be after him.

‘The other guy looking for Jo-Jo will play a lot rougher,’ I said. ‘If I found him, I could help.’

It was at this exact moment that I knew I had a real case on my hands. I was not just wasting time on a boy’s bad hunch, and Jo-Jo Olsen was not sunning himself on a cosy beach. My wild shot hit home.

Swede looked like he’d been kicked in a tender place. Magda Olsen froze into stone. Swede sweated through the fresh suit jacket. Swede was worried wet. Magda was worried, too, but she was also determined. She was determined to follow the course of action they were on, whatever that was. And I had a strange feeling about Magda and Swede Olsen. Call it a sensation. Call it an opinion. They were worried, yes. But they were not worried about Jo-Jo. They were worried about themselves.

‘Tell me about the other guy,’ I said.

‘Beat it,’ Magda Olsen said.

‘Did Jo-Jo see that cop mugged?’

‘Get lost, mister!’ Magda said.

If I had had Swede alone, I think I could have made some progress. As it was, I was ready to go on with the dance. I did not have the chance. Two men entered from some other room, and the music stopped. They were boys, not men, but they were big boys. They looked enough like Swede to tell me that I was looking at two of Jo-Jo’s brothers. There was a girl behind them. The girl was pretty. The boys were not.

‘Take off,’ one of the blond boys said.

‘My mother said get lost,’ the second giant said.

I had the pistol in my belt. I did not even show it this time. The two boys looked about as dumb as Swede, and they did not have his forty-odd years of learning that caution pays. They had not had all the long, hard years to develop doubts. They would not hesitate. I turned without a word and went.
