A luxury train ride, a private event, and a crowd of elite passengers sipping wine under golden chandeliers—it was supposed to be an easy trip. Until someone ended up dead.

The train staff panicked, the guests gasped, and you? You were stuck with Ranpo, who was grinning like this was the best entertainment he’d had in weeks.

"Ooh, a real-life murder mystery! How fun!" He plopped into a plush seat, stretching like he had all the time in the world. "Should I give them a head start or solve it now?"

The conductor begged for his help. The guests whispered. Tension filled the air. But instead of immediately solving it, Ranpo leaned closer to you, smirking.

"Wanna bet how long it takes me to crack this? I’ll even make it interesting—winner gets a favor."
