An old sea captain was found murdered in his seaside cabin. The calendar on the wall showed the date was Tuesday, October 14th. The milkman told Detective Brooks he delivered milk on Sunday, Monday, and Tuesday mornings, but noticed something wrong on Tuesday and called the police. What tipped off the milkman?
Monday's milk
If the milkman delivered milk on Sunday, Monday, and Tuesday, but the captain was found dead, Monday's uncollected milk would still be sitting on the porch, or the milkman would have noticed Sunday's milk uncollected on Monday morning. Wait—the milkman noticed something wrong *on Tuesday* because Monday's milk was untouched, or because milk isn't delivered on Mondays? Let's refine: The milkman wouldn't deliver on a day when previous milk was untouched, or the milkman knew the captain was dead because Monday's bottle was still sitting there when he came back on Tuesday.
