Knox was still trying to prise open the steel balcony shutters when he heard the apartment block's front door slam closed. He looked down over the rail in time to see his assailant, still wearing Augustin's motorcycle helmet, carrying his laptop over to a blue 4x4 in the parking area, too far away for him to make out its licence plate. The man climbed inside before taking off the helmet, giving Knox no chance to see his face. And then he was gone.
Knox turned his attention back to the steel shutter. But he couldn't get through, no matter what he tried. It seemed he was stuck out here until whoever lived here came home. And who could predict how they'd react? They'd almost certainly call the police. He leaned out over the railings. The shutter of the balcony beneath was raised and its glass doors were wide open. He called out. There was no reply. He called louder. Still nothing. He paused for thought. Climbing down to it wouldn't be easy, but he was confident he could manage it safely enough, and it was better than waiting here.
He straddled the railing, turned to face the building, placing his feet between the stanchions. The breeze didn't feel quite so gentle any more, with nothing between him and the tarmac below. He crouched, grabbed a stanchion in each hand, took a deep breath, then lowered himself, legs kicking air above the drop. His stomach and then his chest scraped on the rough concrete. His chin bumped against it, biceps feeling the strain. He tried to adjust his position, give himself a respite, but his grip slipped and he dropped sharply, shuddering to a halt, hanging there holding desperately onto the base of the two stanchions.
It was at that moment that an overweight woman with silvered hair came out onto the balcony. She saw Knox dangling there, dropped her basket of laundry and began to shriek.
