reminds me when I was sharing a house with a friend and I got back late from a gig. He left early in the morning setting the alarm, which I triggered as I walked down the stairs. Although I disabled the alarm, I unfortunatly missed the telephone call from the Alarm company, who informed the police. They ambled round and knocked on the door. After coming in and answering a few questions they left satified I was legitimatly in the house. All the time I was thinking "dont go into the front room".
As my housemate had bought a (deactivated) Bren gun at the weekend and it was sitting in the front room looking all nice and dangerous
