On the hottest July afternoon, a man was found dead inside his locked, air-conditioned study. The window was bolted shut from the inside, and the only door was locked from the inside with the key resting on the desk. The coroner noted no marks of trauma, but Detective Brooks noticed a large puddle of water surrounding the chair and a stack of old newspapers. How did the man die?
He stood on a block of ice
The man stood on a large block of ice to reach a high shelf or hang himself, and as it melted during the scorching July afternoon, it created the puddle while leaving no footprints or signs of entry.
