Tonny and Willy Kok lurked by the door whining to be released. Vos told them straight: no one was going anywhere until he found out what had happened. Then he got the story. The Kok brothers had been on their way back from a few beers in one of the harbour bars. When they approached Stefan Timmers’ place they saw a figure run through the open door and vanish down the street. Van der Berg was inside, half-conscious on the floor. ‘Someone biffed him,’ Tonny said. ‘I’m thinking maybe we should have gone chasing that fellow who skedaddled up the lane. But we were worried about the man here.’ ‘Moaning and groaning,’ Willy added. ‘Very strange. Don’t get this kind of thing in these parts.’ Laura Bakker was with Aisha, checking on the injured detective. ‘What do you mean?’ Vos asked. ‘Well, this is Stefan’s place, isn’t it?’ Willy said as if it was obvious.
