Debbie paused from typing up her report and looked around the office. Everyone was busy working. There was the low mutter of voices and the beat of music coming from the turned down radio.
There was also something else; a high pitched whining sound. It reminded her of the sound of the cleaning drill at the dentist.
She turned to a neighbouring colleague, ‘do you hear that whining sound?’ Debbie asked.
‘What sound? I don’t hear anything.’
The phone ring and the colleague answered it.
Debbie shook her head but she carried on hearing the sound.
She checked her PC and those of her neighbours, she turned the radio on and off, asked around the office and tried hard to find the source of the noise but couldn’t located it.
Leaving the office, the sound was still whining in her ears. Debbie crossed the car park and looked over the road, there were builders digging.
Debbie turned and walked over to them till she could see clearer that one of the builders had a scanning device.
‘It runs right here!’ that builder called, ‘mark it up!’
Debbie sighed, the noise was solved. She wasn’t going insane after all.
