The rain was pouring down heavily, creating a deafening noise on the tin roof of the small

market square. The vendors had packed up their stalls and left, leaving behind a few stray

dogs and rats scavenging for food. The street lights flickered, casting eerie shadows on the

wet pavement.

In the middle of the square, a wooden pole stood erect, supporting a tattered banner that

read "Welcome to Trikone". The banner had been there for years, ever since the town had

been renamed Trikone by the local politician who claimed it was a symbol of unity and

harmony.

But on that fateful night, the pole had a new addition: three severed human arms, tied

together with a rope, forming a grotesque triangle. The arms were pale and bloodless, with

jagged cuts at the wrists and elbows. They hung from the pole like a macabre ornament,

swaying in the wind.

A loud scream pierced the air, startling the animals and breaking the silence. A young

woman, who had taken shelter under a nearby shop's awning, had spotted the horrific

sight. She dropped her umbrella and ran towards the nearest police station, screaming for

help.

The police arrived within minutes, followed by an ambulance and a forensic team. They

cordoned off the area and began their investigation. The woman who had discovered the

arms was taken to a nearby hospital for treatment of shock.

The police inspector in charge of the case was , Rajesh Banerjee(Ritwick's father). He was a

tall and muscular man, with a thick moustache and piercing eyes. He had been in the police

force for over two decades, and had seen his fair share of crimes. But this was something

else. This was beyond his comprehension.

He examined the arms carefully, looking for any clues or marks that could identify them. He

found none. The arms were clean and devoid of any tattoos, rings, or fingerprints. They

looked like they had been washed and sanitized before being severed.

He turned to his assistant; a young constable named Ravi. "Have you checked the CCTV

footage?" he asked.

"Yes, sir. There are four cameras in this square, but none of them captured anything useful.

The rain was too heavy, and the lights were too dim. The footage is blurry and grainy." Ravi

replied.

"Damn it." Rajesh cursed. "What about the witnesses? Did anyone see anything?"

"No, sir. The woman who found the arms said she didn't see anyone or anything suspicious.

She said she was waiting for her husband to pick her up from work when she noticed the

arms hanging from the pole." Ravi said.

"Did she recognize any of the arms? Did they belong to anyone she knew?" Rajesh asked.

"No, sir. She said she had never seen them before." Ravi said.

Rajesh sighed and rubbed his temples. He felt a headache coming on. This case was going to

be a nightmare.

He looked at his watch. It was almost midnight. He decided to call it a day and resume the

investigation in the morning. He instructed his team to take the arms to the forensic lab for

further analysis and report back to him as soon as possible.

He got into his car and drove home, hoping to get some sleep before facing another day of

horror.

Meanwhile, in another part of the country, two young men were sitting in their apartment,

watching TV and munching on popcorn. They were Kalicharan Bhattacharya and Ritwick

Banerjee, students of neurology at one of the most prestigious universities in India.

Kalicharan, or Kali Da as he was affectionately called by his friends, was a second-year

student who had a passion for solving mysteries and puzzles. He loved reading detective

novels and watching crime shows. He had an eidetic memory and a keen sense of

observation. He often helped his professors with their research projects and experiments.

Ritwick was a first-year student who had joined Kali Da's apartment as his roommate a few

months ago. He was friendly and cheerful, always cracking jokes and making fun of himself.

He admired Kali Da's intelligence and skills, and often sought his advice on academic

matters.

They had become good friends over time, sharing their interests and hobbies.

Next day on evening, Ritwick rushed into their apartment, drenched and pale. He threw his

backpack on the sofa and collapsed on a chair. Kali Da looked up from his laptop, concerned.

"What happened, Ritwick? You look like you've seen a ghost."

Ritwick shuddered and took a deep breath. He recounted a chilling incident that had occurred

in his hometown, a small town named Trikone in West Bengal. Three severed arms had been

found, joined together to form a gruesome triangle, hanging from a pole in the middle of a

market square. The police had been baffled, unable to determine who could have committed

such a heinous act.

Kali Da's detective instincts were immediately ignited by the macabre story. He asked Ritwick

several questions, trying to gather more details. Ritwick said that his father had called him

and told him about the case. He also said that he had seen some photos of the crime scene

on his father's phone.

"Can you show me those photos?" Kali Da asked eagerly.

Ritwick hesitated, but then nodded. He took out his phone and opened a chat with his father.

He scrolled through the messages and found the photos. He handed the phone to Kali Da,

who examined them carefully.

The photos were disturbing, to say the least. The severed arms were bloody and mutilated,

with jagged edges where they had been cut off. They were tied together with ropes and hung

from a metal pole that had been erected in the center of the market square. The pole was

surrounded by yellow tape and police officers. A crowd of curious and horrified spectators

had gathered around the scene.

Kali Da felt a surge of adrenaline as he studied the photos. He noticed some details that

caught his attention. The arms were all left arms, and they all had tattoos on them. One had

a snake, another had a rose, and the third had a star. The tattoos looked familiar to Kali Da,

but he couldn't place them.

He zoomed in on the photos, trying to see if there were any other clues. He saw something

that made him gasp.

"Ritwick, look at this!" he exclaimed, pointing at the screen.

Ritwick leaned over and looked at what Kali Da was showing him. His eyes widened in shock.

"What is that?" he asked.

"It's a microchip," Kali Da said. "A tiny electronic device that can store information or perform

functions."

"Where is it?" Ritwick asked.

"Here," Kali Da said, zooming in further. "It's embedded inside one of the arms, near the

elbow."

He showed Ritwick the photo of the arm with the snake tattoo. There was a small bump on

the skin, barely visible to the naked eye. Kali Da had spotted it because he had seen similar

devices before in his neurology studies.

"What does it do?" Ritwick asked.

"I don't know," Kali Da said. "But it must have some significance. Why else would someone

implant it inside an arm?"

He looked at Ritwick with a determined expression.

"We have to find out," he said.

He urged Ritwick to inform his father that they intended to visit the town and investigate the

case. Ritwick was reluctant at first, but Kali Da convinced him that they could help solve the

mystery and catch the culprit.

Ritwick called his father and told him about their plan. His father agreed to let them come,

but warned them to be careful and not interfere with the official investigation.

Kali Da packed his bags and prepared for their journey. He felt excited and nervous at the

same time. He had always dreamed of solving a real-life mystery, but he never imagined that

it would be so gruesome and horrifying.

He wondered what secrets lay behind the triangle murders.
