A famous author was murdered in his writing studio. On his desk, a calendar page for July 15th was circled in red ink. Next to it was a mug of steaming coffee and a half-eaten bagel. The detective checked the victim's wristwatch, which had stopped when he fell, reading 8:00 AM. A calendar page for July 15th cannot be correct if the murder happened in winter, but that wasn't the flaw. The flaw was the date itself. July 15th of that year was a Sunday. Why did the detective arrest the neighbor who claimed he spoke to the author on that exact morning?
July 15th was a Sunday
The neighbor claimed he spoke to the author on his way to work that morning. People do not commute to regular jobs on a Sunday, exposing the neighbor's lie.
