The Mystery Clock Case: A Short Detective Story

Detective Max, a man etched with the map of countless late nights and mysteries, stared out at the scene. The antique shop, Tick-Tock Treasures, was usually a haven of polished wood and delicate bells, but tonight it was a picture of shattered glass and upturned windows. Mr. Abernathy, the shopkeeper, a thin man with glasses perched precariously on his nose, wrung his hands. “My precious watch, Detective! The Emperor’s Chronometer! It’s gone! Vanished into thin air!” The Emperor’s Chronometer was legendary, a timepiece made for an emperor of the Qing Dynasty, encrusted with jade and gold. Its value was astronomical. Max surveyed the damage. The front door had been forced open, but there was no other visible sign of intrusion. The alarm system, however, had been cleverly disabled.

“Mr. Abernathy, how many people knew about the chronometer and its location in the store?”

“Very little. Naturally, I am referring to myself. My assistant, Elsie, has been with me for years. And… well, two potential buyers were here yesterday, genuinely interested. Mr. Silvers and Mr. Blackwood.”

Max interviewed Elsie first. She was distraught and claimed that she had locked up the shop the night before, as usual. She swore she didn't know who did it and hadn't told anyone about the stopwatch.

The interviews with the potential buyers followed. Mr. Silvers, a large man in a pinstripe suit, was indignant.

“Detective, I’m a respectable businessman! I wouldn’t dream of stealing something like that. I left Abernathy’s store around 4:00 PM yesterday. I was at a board meeting until 7:00 PM and then had dinner with my wife.” He offered a series of names as alibis.

Mr. Blackwood, a wiry, intense man with darting eyes, was more evasive. “I was there, yes. I was interested in the watch, of course. But I decided it wasn’t for me. I left… around 5:00 PM, I think. I went straight home. I was reading. He offered no alibi, his gaze still flickering to the floor.

Max paced the small office, the air heavy with the scent of old wood and dust. He had a strong intuition that one of these three was dishonest. He just needed the right question.

Upon his return to the store, he scrutinized the display case containing the chronometer. He noticed something subtle—a faint streak of oil on the polished wood near the watch stand.

He called the three suspects back into the store. One by one, he asked them the same question, wording it carefully:

“Imagine looking directly at the watch in its case. To get the watch with your right hand, would you need to push it up, down, or sideways?

Elsie, tearful and hesitant, replied, “I… I guess upward. The object was on a stand.”

Mr. Silvers, seething with indignation, declared, "Up, of course! What question is that?"

Mr. Blackwood paused, narrowed his eyes, and said, "Down." You'll have to push down slightly to release the safety before you can lift it."

Max smiled, a grim, tight smile. "Thank you, gentlemen. Mrs. Elsie, thank you as well. Mr. Blackwood, I'm afraid I'll have to ask you to come with me.

The Logic Puzzle:

How did Detective Max figure out that Mr. Blackwood was the thief based solely on his answer?

Solution:

Here's how Max cracked the case:

The faint streak of oil on the display case was the clue. He surmised that someone had touched the case following its cleaning, likely during the removal of the watch.

Max designed his question to uncover crucial information that only the thief would be aware of. Mr. Abernathy had not mentioned a safety catch on the clock stand. Only someone who had actually touched the clock and therefore attempted to remove it would know of this detail. Elsie and Mr. Silvers would have made an upward lifting motion since they were simply observing the clock on a stand and not attempting to steal it. Blackwood's knowledge of the "downward" force to release the safety catch betrayed his firsthand experience with the theft.
