Mr Harrison was killed on 16th March 2004. It was a Sunday. His wife was on holiday visiting his mom, the son was in the pool, the dog was digging up the garden, the daughter was in the dinning room, waiting for the Butler who was in the kitchen to bring the food and the made was getting the mail. Who killed Mr Harrison?

The maid did it.

The made,(which is spelled maid and butler is not capitalized). There is no mail delivery on Sunday.

Dumb riddle. I often wait until Sunday to get the mail.

But Joy....if you were my maid and I was paying you and you only got the mail on Sunday, I would fire you. Just sayin :p
