What lies behind the door of Number 4? Spooky mysterious fun for the brave!

A stolen artifact said to have special healing powers has been stolen from a local museum. Local police have traced it to Number 4 - a dingy studio flat previously occupied by a mysterious figure seen only fleetingly by locals and only ever in the hours of darkness. Despite knowing where the artifact is, the police are seemingly unwilling, or afraid, to cross the threshold to retrieve it. Your task? Enter and retrieve the artefact before making your escape...but there's only an hour until sun-up and the property's new occupant arrives so you'd better hurry!
