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

*Scotland Yard, Interrogation Room — 3:00 PM*

Margaret Wilson sat perfectly still, her hands folded on the steel table. The fluorescent lights hummed overhead, casting a sterile glow over Captain James Morrison and Detective Thomas Wilson as they leaned in, their gazes unrelenting.

"We know you did it," James said, his voice low and deliberate. "John's death wasn't sudden. It was *designed*."

Margaret's eyes flickered, but her voice remained steady. "I loved my husband. Why would I harm him?"

Thomas slid a forensic report across the table. "Penicillin overdose. Traces were found on your nightstand glass."

She didn't flinch. "I've been ill. The doctor prescribed it. Check the records."

James's jaw tightened. "The Ghost contacted you, didn't he? Threatened you? Made promises?"

"I don't know any 'Ghost,'" she said coldly. "You're grasping at shadows because you failed to protect John."

Thomas leaned closer, his tone sharpening. "Your child's school was contacted last week. Strange calls. Odd messages. Care to explain?"

For the first time, Margaret's composure cracked—a faint tremor in her fingers. "Leave my son out of this."

"We *can't*," James pressed. "Because the Ghost doesn't stop here. He'll use you again. Or worse—target your boy."

Margaret's lips thinned into a line. "I want a lawyer."

The detectives exchanged a frustrated glance. She hadn't confessed.

*Victor Black's Apartment — Earlier That Day*

Victor lounged in an armchair, sipping Earl Grey as he watched the interrogation live-feed on a encrypted tablet. Margaret's defiance played out in pixels.

He'd coached her meticulously: deny, deflect, demand legal counsel. No evidence tied him to her. The penicillin? Untraceable. The threats? Burner phones and proxy servers.

His phone buzzed—a message from an anonymous number:

**She's holding. Proceed to Phase Two.**

Victor smiled. The board was set.

*Kensington Manor — Night of the Murder (Flashback)*

Margaret had followed every instruction.

1. **Feign illness.** A cough, a fever—enough to justify the penicillin.

2. **Lure John.** A silk nightgown, a whispered promise.

3. **The Poison.** A cream laced with concentrated penicillin, applied where John's "habits" would ensure ingestion.

He'd died clawing at his throat, his face purpling. Margaret had lain motionless until dawn, then scrubbed her skin raw in the shower.

*Interrogation Room — Present*

James stood abruptly, his chair screeching. "We'll find the Ghost. And when we do, your cooperation—or lack of it—will determine your son's safety."

Margaret's voice trembled, but her words were iron. "I. Didn't. Kill. Him."

The detectives left the room, the door slamming behind them.
