So it's four in the morning. The thing has gone off once before already. He rings up the police who say they can't do anything if the person with the key won't wake up and come around. Finally they get the owner in but he slips away before there can be words. Everything settles down, it's all quiet and Michael just about gets to sleep when the alarm goes off again.
Something snapped. Michael went to his tool box and leaned out of his window and hit the bloody thing with a hammer. He banged and banged and finally the thing falls right off the wall. They'll know it's him, but they should have fixed it.
Michael snuggles down into himself and dreams of caressing the smooth flesh of his wife, ample like clouds in heaven. He sinks down into deep and cushioned sleep.
