You’re a detective from Graves Detective Agency. Your boss, Evelyn Graves, was hired by Victor Vantrell, the 68-year-old CEO of Vantrell Industries, the largest tech company in the world. His daughter, Mia Vantrell, had been murdered, and he wanted answers. Evelyn took the case, and you, her assistant, joined her.

You soon discovered the likely killer was Howard Bixby, a 45-year-old obese tech worker. You also learned he had stolen experimental helmets supposedly meant for mind-reading. While tracking him down, you found Howard dead in his office—killed exactly like Mia.

Security footage revealed the last person to see him alive was Sofia Delaine, the 18-year-old model Victor was controversially dating. Evelyn suspected Sofia, but nothing about her suggested motive or connection to Howard.

Then things became stranger: Victor intended to leave all his wealth to Sofia. Shortly after, Sofia herself was found murdered, identical method, identical pattern.

Only Howard could have killed Mia. Only Sofia could have killed Howard. Only Victor could have killed Sofia. Yet all three murders were the same.

Victor called Evelyn claiming he had new evidence and trusted only her. You argued, but she went alone, armed. She told you to use the opportunity to search his office.

In his office you found one clue: a USB labeled “bswap.hlmt.” No device could run it.

Evelyn then called you to a lab. Victor lay dead, face purple. She said she found him like that. Pills with his fingerprints suggested suicide. But beneath his hand you saw blood forming a message:

“BOSWAP HELM.”

Near him was a trash can with two burned helmets. You secretly took them. Evelyn insisted the case was closed.

At home, you examined the helmets. Your PC finally ran the file. They weren’t mind-reading devices—they were body-swap helmets.

Everything clicked:

Howard stole the helmets.

Mia caught him, so he killed her.

He swapped bodies with Sofia to inherit Victor’s wealth.

He killed Sofia while she was in his body.

He then swapped bodies with Victor and killed him.

In Victor’s body, he called Evelyn and swapped with her, forcing her into Victor’s dying body and making her take the pills.

Before dying, Evelyn, trapped in Victor’s body, wrote the blood message.

You cried—it was the only explanation that made sense.

Your grief stopped when your PC and the helmets suddenly burst into flames, completely burning away the evidence.

The next morning, you found “Evelyn” calmly reading files. Angry, you slammed the desk and told her to drop the act. You explained your entire theory.

She laughed, clapped, and said you’d solved most of it.

But you were wrong about one thing: She wasn’t Howard.

She was Sofia Vantrell.

You were stunned—she was the first victim. Why would she do all this?

She sighed and told you the truth: she was furious her father planned to give everything to Sofia Delaine. All the technology that made Vantrell Industries rich had been her inventions since she was five, yet Victor took all the credit. And now he wanted to hand it all to “some useless model.”

Wronged twice, she formed her plan: kill Victor, swap bodies with Sofia Delaine, and claim everything while living as her.

But Howard discovered the plot and tried to warn people. Panicking, she swapped bodies with him and killed him—setting the entire disaster in motion. Long story short, she swapped bodies and killed everyone, ending up in Evelyn’s body. She leaned back in the chair and smirked, amused by your expression.

“You really didn’t notice?” she said. “In the lab… that wasn’t Evelyn anymore. That was already me.” She tapped her temple. “And thanks to the memories I get from every swap, I knew exactly how to act, what to say, what Evelyn would do. Perfect imitation.”

You clenched your fists as she stood and stretched calmly, wearing Evelyn’s face like a mask.

“Sadly,” she continued, “I can’t recreate the helmets. I don’t have the tech, or the access, or the resources. Everything burned. So congratulations—” she smiled, “—we’re stuck with each other"
