Thanks John. The answer has to be connected with entertainment, so casinos would work, if there was some connection with the monarch's school. As the answer only has 7 letters the offence bit has to be quite a small word like sin. Ideas for the monarch's school are Eton (founded by one of the Henrys) or KEGS (King Edward VIII Grammar School, which is in Chelmsford, local to where the quiz is set. Any other ideas will be much appreciated!
