No Smoke, No Mirrors

I am not a very practical person. In the event of anything going wrong about the house, I am more likely to reach for my wallet or the telephone than a toolbox. It was a close run thing then when the smoke detector started bleeping - once a minute. A couple of hours before bedtime this intentionally loud noise is not an attractive proposition. We knew that our smoke detectors are connected to the mains and did not expect additional batteries. However, we did discover the 9v battery and the related instructions INSIDE the detector cap.

Armed with this knowledge we went to one of our mercifully late opening shops and bought the necessary battery and replaced the old one. Not much, you might think but for me........
