You hear a noise. It’s past midnight.
So what do you do?
You hop up, turn on a few lights, tramp down the passageway. open and close cupboards, bang doors, make a lot of noise.
Then you stop and listen.
There it is again.
Those bloody mice, you say, though you’ve seen no evidence of any.
It’s nothing, you decide, nothing. House noises.
You head back to the bedroom, turn off the lights.
Someone taps you on the shoulder.
