Well it's like this....It was the butler in the kitchen with the candlestick! (hehehe just kidding)
you are both quite right it was clue inspired and the lady expressing herself so vehemently about who she thinks killed the old man isnone other than Miss Scarlet, while a very unconvinced Mr. Mustard and Miss Peacock listen to her ramblings on the subject.....those three characters were my favorite to play when I played clue as a kid therefore when I found the background thats what it reminded me of, if you look real close at Scarletts feet shes standing in the middle of a bloodstained carpet thats outlined with a chalk drawing of the poor old man that got it. Anyway thank you for the comments I appreciate them!
