As the noise of the explosion rattled the roof slates around her, Lin Lee smiled in triumph. She couldn’t be sure of the extent of the damage, but judging from the vibrations the force was significant. She felt confident that at the very least she had destroyed the Harmoniser, completing the mission set for her by the Chairman. She considered heading back toward the utility shed on the roof above the explosion site to survey the damage, but decided this would be too risky as the whole structure of the building would be highly unstable. She looked back down to where the vans of the bomb disposal team were parked. There were two guards stationed at the entrance to the building and another guard positioned at the barrier leading into the car park. She chose to stay put a little longer to observe their movements. Trying to make herself comfortable, she thought she heard the sound of a nearby building collapsing. A low rumbling noise in the distance growing gradually louder. A bright light appeared, coming from the direction of the noise. Suddenly a helicopter swooped toward her. It swung around in a steep arch directly above her before settling into a hover just metres from where she sat. The wind from the rotors blew dust into her eyes. She raised her hands to protect them. She could just about see the side door to the helicopter was open revealing a uniformed man with a rifle pointing directly at her. Before she had chance to get out of the way she heard the snap of the rifle and felt an intense pain explode in the top of her left arm. She rolled into the gutter at the edge of the roof and leopard crawled along the narrow walkway it formed. She could still hear the roaring noise of the helicopter above her. The pain in her left arm was excruciating but she managed to drag herself out of sight. She stood up and continued along the walkway, heading back toward the roof above the bomb site. As she approached she could see part of the roof near the utility shed had collapsed. The helicopter was approaching from behind her so she had no choice but to continue forward. As she drew nearer to the site of the explosion the roof was littered with chunks of brick, dislodged slates and twisted metal from the gutter. She edged forward slowly but her left foot pressed onto a loose slate. It shot from under her and she stumbled backward, unable to steady herself with her injured arm. She fell heavily onto the roof in an area where the tiles had been blown clear. The roof gave way and she plummeted downwards until her body stopped abruptly, impacting hard against a pile of rubble two floors down. She lay motionless, her back arched at an unnatural angle against the hard mound that had broken her fall.
