The Fourth Day
When you go to the bathroom in my apartment, you'll hear an alarm going off. The sound comes in through the bathroom fan, and the only other place in London that it can be heard is in my living room. You can't hear it on the street below my apartment; the grocery shop on the ground floor doesn't know anything about it; and the holes in the bulletproof plastic next door at the minicab company don't even let in enough sound to get a response to neighborly questions.
