So there was a family who lived in a round house. One day there was a murder and the mom disappeared! The police came to the round house and asked the dad if he did it. The dad said "no I was at work". Then they asked the daughter if she did it but she said "no I was playing with my dolls". Then they asked the brother the same question and he said "wasn't me I was playing video games". Final they asked the maid who did it and she said "nope not me I was cleaning the corners".
So who did it?
