READING TIME INFO: 12-15 minutes

The Crime: A Mystery Story Begins with Death

The Impossible Scene

It was 9:47 AM on a gray November morning when Detective Sarah Chen received the call that would occupy her for the next forty-eight hours. Theodore Blackwood, renowned clockmaker and watchmaker for the past five decades, had been discovered dead in his workshop.

The Facts:

Location: Blackwood’s Clock Repair, Third Avenue
Victim: Theodore Blackwood, 68 years
Time of death: Between 10 PM and midnight (approximate)
Discovery: 9:30 AM by his apprentice, Marcus Webb
Cause of death: Blunt force trauma to the head
Weapon: Heavy brass clock pendulum, discovered lying beside the body

However, what made this mystery story so exceptional was that the workshop was locked from the inside.

The Locked Room

Sarah surveyed the area with expert eyes. This was her area of expertise—impossible crimes that challenged logic. The workshop presented a curious scenario:
Evidence at the scene:

Front door: Locked with deadbolt, key on inside hook
Back door: Locked, key in Theodore’s pocket
Windows: All latched from inside, undisturbed
Skylight: Closed and painted years ago
No hidden passages: Solid brick walls, concrete floor
Security camera: Revealed no one entered after Theodore at 6 PM

Each great mystery story poses the central question: How was this possible?

The Investigation: Detective Mystery Story Unfolds

Clue #1: The Stopped Clock

Sarah observed something strange. In a workshop where there were hundreds of ticking clocks, seven of them had stopped at 11:43 PM.

The stopped clocks:

Grandfather clock near the body
Wall clock above the workbench
Pocket watch on Theodore’s desk
Mantle clock by the window
Two cuckoo clocks
Antique Ship’s Chronometer

“Why these seven?” Sarah murmured. “And why all stopped at the same time?”

In the finest detective mystery stories, no detail is ever insignificant. Theodore was a perfectionist. He would never let his clocks run down and stop.

Clue #2: The Unfinished Repair

On Theodore’s workbench was a disassembled pocket watch. The watch was a Patek Philippe, costing at least $15,000. The arrangement of the tools around the watch was precise. However, the watch’s repair was unfinished.

Observations:

The watch had once belonged to a man known as Victor Crane, a local real estate developer
The ticket for repairing is dated three days ago
Theodore: “Mainspring replacement – delicate work.”
Work seemed to have been abandoned in progress

“Theodore never left any work unfinished,” the apprentice, Marcus, insisted. “He’d work until 2 AM, if necessary, to finish a repair job. This isn’t right.”

Clue #3: The Mysterious

Sarah flipped through Theodore’s appointment book. The final entry was scribbled in shaky handwriting: “9 PM – V.C. – FINAL DISCUSSION.”

V.C. Victor Crane. The owner of the unfinished watch.

Background on Victor Crane:

A real estate developer recently bought several buildings on Third Avenue
Wanted to buy Theodore’s shop to develop it
Theodore has said no several times before.
Last meeting ended in a “heated discussion” per witnesses.

This is the plot of the mystery story, which adds a prime suspect.

The Suspects: Classic Mystery Story Elements

Suspect #1: Victor Crane – The Developer

Sarah interviewed Victor Crane within his lavish downtown office. He was seated within his mahogany desk, the expansive watch on his wrist not the one that was sent out for repair.

Victor’s statement:

Yes, I did have a 9 PM appointment with Theodore. I was going to make another offer on his property. However, I went nowhere. My assistant rang me with news of an emergency at the Riverside project. I was there between 8:30 PM and midnight. There are twenty witnesses to vouch for my presence.

Alibi check:

Assistant verified emergency call 8:25 PM
The security log confirms that Victor entered the Riverside building by 8:35 PM
Presence till 11:58 PM confirmed by videos
Solid alibi

Sarah noticed how he relaxed when she brought up this alibi. Too much relief?

Suspect #2: Marcus Webb – The Apprentice

Marcus had been working under Theodore’s guidance for three years. He was good-looking, charming, and only 28 years old, facing financial challenges despite being paid low wages by Theodore, who claimed it was good for “building character.”

Motive investigation:

Marcus recently applied for loans to start his own shop.
Rejected for lack of capital
Theodore would not lend him any money.
By the will, Marcus was to inherit some of Theodore’s tools.
No alibi for time of death-home alone

“I loved Theodore like a father,” Marcus said, his voice breaking. “Yes, we argued about money. But I’d never hurt him. Never.”

Sarah saw real sorrow in his eyes. Yet, in detective mystery stories, looks can deceive.

Suspect #3: Evelyn Blackwood – The Estranged Daughter

His daughter had moved to California fifteen years ago following a dispute over her career choice with her father. She became a successful tech entrepreneur while her father stayed in his small clock shop.

Recent Developments:

Evelyn flew in two days before Theodore’s death.
She had dinner with Theodore the night before he died.
Witnesses say dinner ended with raised voices
Evelyn was a guest at the Grand Hotel, no alibi for time of death
Stood to inherit the shop and Theodore’s estate

“We were trying to work things out,” Evelyn said, wiping her eyes. “I wanted him to retire, move to California. He wouldn’t. Said his clocks needed him. We had a fight, but I left around 9 PM. Never saw him again.”

Suspect #4: Dr. Raymond Pierce – The Collector

A wealthy antique clock collector who had been trying to buy a rare 18th-century clock from Theodore for years.

Suspicious behavior:

Called Theodore several times in the past week
Offered $200,000 for the antique clock (worth $50,000)
Theodore always refused
Dr. Pierce said he was at a medical conference during the time of death
Conference records showed he was at the 9 PM session
But his hotel room was only 10 minutes from the clock shop

“Theodore was being obstinate,” Dr. Pierce said icily. “But I’m a collector, not a killer. I buy things legally.”

The Breakthrough: Mystery Story Solution Emerges

Clue #4: The Coffee Cup

Sarah returned to the workshop, examining details that her team had photographed. A coffee cup was on Theodore’s desk. Forensics found two sets of fingerprints: Theodore’s and an unknown set.

More importantly, the cup was half-full. Theodore never left coffee unfinished. He was famous for drinking it to the last drop.

Someone had been there. Someone Theodore served coffee.

Clue #5: The Window Latch

“Detective, you should see this,” the forensics tech called.

The back window’s latch seemed to be locked from inside, but magnified, minute scratch marks indicated it had been tampered with. The latch could be locked from outside with a thin wire.

The technique:

Window could be opened from outside
Person enters workshop
Pulls window shut
Uses wire through small gap to flip latch
Appears locked from inside
Wire removed, gap invisible to casual inspection

The “locked room” wasn’t impossible after all. Classic mystery tales often conceal straightforward answers in complicated puzzles.

Clue #6: The Prescription Bottle

In Theodore’s trash bin, Sarah found an empty prescription bottle. Heart medication. Prescribed by Dr. Raymond Pierce.

“Why would a clock collector be Theodore’s doctor?” Sarah wondered aloud.

Background check revealed Dr. Pierce wasn’t just a collector. He was Theodore’s physician and had been for twenty years.

Clue #7: The Repair Records

Sarah studied three years of repair records. Victor Crane brought watches for repair every month. Always expensive ones. Always collected promptly.

But not this one.

This Patek Philippe had been waiting for three days. Victor hadn’t called. Hadn’t checked on it. For a man who cared for his possessions with obsessive zeal, this was odd.

Unless the watch was never the point.

The Solution: Detective Mystery Story Resolved

Connecting the Clues

Sarah presented her case in the conference room:

The timeline reconstruction:

9:00 PM: Theodore waits for Victor Crane, but Victor doesn’t show up
9:30 PM: Another person arrives—Theodore knows them, makes coffee
11:43 PM: Seven clocks stop—probably when the lights flickered briefly
11:43-11:50 PM: Murder takes place in darkness
11:50 PM: Murderer escapes through window, locks it from the outside
Midnight: Workshop looks secure from the inside

“The seven stopped clocks,” Sarah told her captain. “They weren’t stopped by the killer. They stopped because of a brief power outage recorded by the utility company at 11:43 PM. Most clocks automatically reset, but these seven older clocks stopped.”

“The killer took advantage of the outage. Waited for the darkness, then struck.”

The Confrontation

Sarah set up a meeting at the clock shop. All suspects were there.

“Victor, you made the opportunity,” Sarah began. “The phony appointment. You never planned to come, but Theodore expected someone at 9 PM.”

Victor went white. “I—I don’t get it.”

“Dr. Pierce, you knew Theodore’s schedule. You’d been his physician for twenty years. You knew about his heart trouble. You knew he worked late.”

Dr. Pierce said nothing.

“But the true killer…” Sarah turned to Marcus. “Was you?”

The Confession

Marcus’s face fell apart. “How did you know?”

The evidence against Marcus:

The coffee cup: His fingerprints
The appointment: He knew Victor wouldn’t come (Victor’s assistant was his girlfriend)
The window: He knew how to manipulate the latch (Theodore taught him)
The unfinished repair: He stopped Theodore mid-work
The motive: Financial desperation + inheritance
The opportunity: Access to shop, knowledge of security
The method: Waited for power outage, attacked in darkness

“I never meant to kill him,” Marcus whispered. “I just wanted to talk about the loan. But he refused again. Said I needed to ‘earn’ it like he did. I got angry. The pendulum was right there. When the lights went out, something in me just… snapped.”

“You staged the locked room,” Sarah continued. “Used your knowledge of the workshop. Made it look impossible. But you forgot—Theodore trusted you. He made you coffee. And you forgot about the fingerprints.”

Marcus broke down completely as officers led him away.

The detective mystery story solved the case, and justice was served

The Epilogue: Mystery Story Conclusion

Aftermath

Victor Crane bought the building of the clock shop but donated it to a local horological society in memory of Theodore. Evelyn Blackwood established a scholarship for young watchmakers. Dr. Pierce’s collection of rare clocks was donated to a museum.

Detective Sarah Chen went back to her office, where another impossible case was waiting.

Lessons from this mystery story:

The simplest explanation always lurks behind the complexity
Trust, once broken, leads to fatal results
Each detail is crucial in detective work
Emotions of human beings are the most unpredictable factor
Justice, though late, always finds its way

Theodore’s hundreds of clocks were given away to new owners, but they kept on ticking endlessly, marking time and waiting for the next mystery story to be revealed.
