It was a dark evening. You sat on the bed and read a book while the cool wind passed through the slightly open window, which moved slightly beneath it. Your boyfriend was at work until late, as always, because he worked as a doctor and preferred to get everything done in one day, so you stopped worrying too much about him while he was away. Suddenly, from the corridor there was the sound of doors opening and the click of lights being turned on. Someone entered the house leisurely, slowly closing the door behind them and taking off their shoes. There was absolutely no doubt about who it could be.
