The police received a call. A person who claimed to be the Ghost said that he was going to kill someone in three days. What's more, the other party hoped that the police could immediately dispatch officers to protect this person, and he intended to complete the hunt under the police's tight protection.
 
In response to this, the police attached great importance to it and made thorough arrangements. When the three-day period arrived, the result was beyond everyone's belief. The target was dead!
 
However, this was just the beginning.
 
The Ghost's goal was to complete 99 perfect crimes and kill 99 enemies.
 
Thus, one perfect crime after another occurred, and the biggest serial murder case in history came into being!

The Ghost in the Dark Night: The Ultimate Revenge Strategy

Victor Black lingered by the water's edge, watching blue lights swarm the Kensington villa across the river. Beside him, Eric Matthews snored on a bench, reeking of beer and barbecue. A faint smirk tugged at Victor's lips.

He crushed a melted SIM card under his heel and hailed a taxi.

*Scotland Yard, Serious Crime Unit — 9:00 AM*

The conference room hummed with tension. James Morrison slumped at the head of the table, shadows bruising his eyes. Around him, detectives hunched over coffee cups, their exhaustion palpable.

"The commissioner wants this solved in *thirty days*," James rasped. "Fail, and we'll all be scrubbing toilets in the Outer Hebrides."

Thomas Wilson stood, his voice raw. "John died between 10 PM and midnight. No forced entry. No strangers in the villa. Surveillance footage confirms it."

A junior detective raised a hand. "What about the windows?"

Thomas's glare silenced him. "Snipers had every angle covered. Not even a fly got through."

James tossed a forensic report onto the table. "No external wounds. Toxicology's pending, but it's poison. Has to be."

"Poison?" A scoff. "The food was screened. Water tested. How'd the killer dose him?"

Thomas leaned forward, knuckles whitening. "Because the killer was already *inside*. Margaret Wilson."

"Inheritance," Thomas said. "John's will leaves her everything. And she had access—sleeping right beside him."

"A smokescreen." James's fist hit the table. "Margaret *is* the Ghost. Or hired him. Either way, she's our lead."

*Victor's Apartment — 1:00 AM*

Victor lounged on his sofa, cigarette smoke curling toward the ceiling. His mind raced—*target two*.

He cracked the door. Eric Matthews swayed outside, clutching a six-pack. "Party's not over, mate!"

Victor forced a smile. "Another time."

As the door closed, he glanced at a photo on his desk: Margaret Wilson, circled in red.
