Knox threw out his hand as he was flung from Augustin's balcony, instinctively grabbed his assailant's wrist, clung on for dear life, breaking his outward trajectory, falling downwards instead, swinging like a wrecking-ball on the man's arm, crashing numbingly hard into the concrete base of the balcony. The impact knocked the wind out of him, strength from his muscles. He lost grip and tumbled down a storey to land flush on the metal railing of the balcony beneath, his left knee buckling beneath him as he fell outwards again, scrabbling desperately for something to cling to, grabbing a cast-iron stanchion as he whirled past, skin flaying from his palm on the speckled rust, until his wrist crashed into the concrete base and ripped him free once more, yet now swinging inwards far enough to hit the rail beneath and fall onto the balcony itself, the breath once more punched out of his lungs, his whole body bruised and sore, but somehow still alive.
He hobbled to his feet, leaned against the railing, looked up to see his helmeted attacker with his visor up, a glimpse of a compressed fraction of his face provoking a shudder of memory; but he vanished before Knox could quite grasp it, or fix his features in his mind.
He looked around the balcony. A steel shutter stood between him and the main body of the apartment. He tried to work his fingers beneath it to prise it up, but without success. He rattled it, pounded on it, trying to attract attention. No one came. He leaned over the railing once more. The car park below was deserted. He was about to call for help when he thought again. Even if he could get someone's attention, they'd surely only summon the police; and he didn't fancy explaining himself to them right now, not while they still held him responsible for Omar's death. Which left him marooned out here while a stranger in a motorcycle helmet plotted ways to kill him.
