Great! Here are four more comprehensive crime mystery stories, each with a different tone and mystery.

### **4. Murder on the Aurora Express Train**

The year is 1934. The exclusive Aurora express train is departing from Paris for Moscow. The body of wealthy industrialist Vladimir Orlov is found in one of the luxurious compartments. The compartment was locked, and there were no signs of forced entry – the case appeared to be a classic "locked room murder."

Detective Sergei Ivanov, who was traveling on the same train, began investigating. Besides the victim, there were three people in the compartment: the industrialist's wife, his secretary, and a mysterious traveler with a last-minute ticket.

Clue: The broken glass of a perfume bottle was found on the floor. The scent suggested a rare fragrance imported by only one company in Moscow.

Solution: The mysterious traveler was a former business associate of Orlov's who had been forced out of business. He used a poison in his wife's perfume to create confusion and force the investigation to focus on bystanders. The Aurora train became the scene of a perfectly planned murder.

### **5. The Mystery of the Hilltop Manor**

England, 1972. The old, isolated Harrington family manor. The owner, Lord Edmund Harrington, is found dead in his library, his family book open beside him, with a single name circled – the lord's younger brother, Henry.

Detective Margaret Clarke noticed that there were no signs of a struggle in the library, but salt and glass fragments were scattered on the floor. The household was visibly shaken:

* Henry – the brother who would gain a vast fortune after the lord's death.

* Julia – the sister, secretly in love with Henry.

* Butler – a loyal servant, knowledgeable of all the family's secrets.

Clue: The glass fragments came from an old ink tank in the library. The salt was used in traditional protective rituals in the Harrington family.

Solution: Butler, who witnessed his brother's plan, tried to warn the lord but was ultimately forced to orchestrate an "accidental" accident. Henry never laid a hand on the lord – the real perpetrator turned out to be Butler, who wanted revenge on the family for past wrongs.

### **6. The Mystery of St. Lucy's Abbey**

Italy, 1493. St. Lucy's Abbey, high in the Alps, becomes the scene of a horrific crime – a monk, Brother Lorenzo, is found dead in his cell, clutching an old parchment with a coded message.

Suspects:

* A young novice who often argued with his brother. * The Father Prior, who hid the abbey's dark secrets.

* An outside merchant, supplying rare books and herbs.

Clue: The parchment contained a code that pointed to buried treasure in the abbey garden. The abbey's detective, Brother Matteo, discovered that the crime was motivated not by greed but by protecting a secret.

Solution: The friar discovered the prior's illegal trade in rare scrolls. Fearing exposure, the prior orchestrated his death, planting false clues in the parchment to pin the blame on the novice.

### **7. Disappearance at a Luxury Resort**

Monaco, 2005. Renowned billionaire Richard Delacroix disappears at a luxury resort during an elegant banquet. His apartment remains locked from the inside, and a note in the window reads: **Time is a thief**.

Detective Laura Moretti is investigating the case. At the resort were:

* A billionaire's wife, who was having an affair with her personal trainer.

* A business rival who threatened to publicly expose the scandal.

* A private assistant who knew all of Delacroix's financial secrets.

Clue: A watch with an invisible scratch on the dial and traces of moisture were found in the apartment.

Solution: The billionaire deliberately disappeared to escape threats from his rival and secure his family's business interests. The note was a clue for the detective to note the "time" – Delacroix left the country, leaving false leads to mislead all suspects.
