A family lives in a round house, they leave there daughter there alone one day, and shes murdered. Working at the house is the butler, the maid, and the chef. The family asks the chef “did you kill the daughter?” He said “no, i was preparing dinner”. They asked the butler “did you kill the daughter?” he said “No, i was hanging up the coats on the coatrack.” They asked the maid “did you kill the daughter?” she said “no, i was in the corner reading a book.”
Who killed the daughter?
We don’t know who killed the daughter. All we know is that the maid is a liar. In fact, I bet no one killed the daughter – the narrator is probably a liar too. And once we determined that the narrator is a liar, there is no reason to believe that the house is round, either.
