Brainteaser: A man was found murdered on Sunday morning. His wife immediately called the police. The police questioned the wife and staff and got the following alibis: The wife said she was sleeping. The cook said he was cooking breakfast. The gardener said he was planting seeds. The maid said she was getting the mail. The butler said he was polishing the silverware. They arrested the murderer immediately. Who was it?
Answer: The murderer was the maid. Mail isn’t delivered on Sunday, so her alibi doesn’t add up.
