She had just poured water into the sink and started to wash up when she noticed the strange sound coming from the washing-machine in the next room. Frowning, she turned off the water, wiped her hands and opened the door to the small bathroom.
The washing-machine seemed to work as usual; the water was on and it was spinning at the right frequency. Still, the strange sound continued.
“How odd”, she muttered to herself, rising from her kneeling position and brushing off her trousers. Perhaps it came from the neighbor’s house; she tended to hear what they were up to and sometimes believe that it happened inside her own apartment.
Shaking her head at herself, she walked out to the sink again and dipped her hands into the hot water. While she scrubbed the plates, the sound behind her increased in intensity.
“What the hell are they doing?” she muttered once she was done and had wiped her hands on a towel. She turned to head out to the door and go bang the others’ door to find out what was making that sound, but she only managed to turn partly when she saw the fire rushing towards her, along with the loud bang that seemed to tear her apart from inside-out.
Her scream was quenched in the flames of the explosion.
