SIL made the Christmas cake, and stored it on top of the fridge. It was brought down to be fed. So BIL fed it, then all 4 of the children (mid to late teens) fed it as well. SIL came back to it, wrapped it and put it back on the fridge. When it was cut, it was lethal. BIL wouldn't let anyone who was driving have any, including the two on duty policemen, who had come to call about a school matter (BIL was caretaker of my secondary school, and lived on site.)
