This exhibition hall was called "Between Hell." Perhaps because of its theme, the lighting inside was extremely dim—so dim that only the outlines of the surrounding exhibits could barely be seen.
Yet with their exceptional night vision, Natsuyu and Lisa immediately spotted the corpse pinned to the wall, a sword driven straight through his body.
Seeing that Ran had not yet noticed the body, Natsuyu instinctively stepped in front of her, blocking her line of sight.
"Natsuyu, what's wrong?" Ran asked, noticing her movement.
"Ran… don't look. There's a body up ahead."
The moment Conan heard that, he tried to rush forward to take a closer look—but before he could even move, a hand suddenly reached out from behind and covered his eyes.
Conan froze.
Who?!
He hadn't heard any approaching footsteps at all. Could the killer still be hiding nearby?
He struggled instinctively, but his body was quickly restrained. Then a low, teasing voice whispered by his ear, soft yet dangerous.
"Don't move, little one~ This isn't something you should be looking at. Curiosity can be very dangerous when it goes too far."
Hearing that it was Lisa, Conan finally relaxed. He knew she had only meant to shield a child from such a bloody scene.
But he wasn't an ordinary elementary schooler—he was a high school detective, Kudo Shinichi. Now that a case was unfolding right in front of him, he was forced to stay away simply because of this child's body.
Damn it… it's all because of those two men in black who did this to me.
"Lisa, I understand," Conan said obediently. "I won't go over there anymore. You can let me go now."
"Conan, something serious has happened. Don't run around and cause trouble," Ran added. She carefully avoided the corpse and held onto Conan's hand to stop him from sneaking off again.
"Okay…" Conan could only reply helplessly.
Seeing that both Lisa and Ran were watching him closely, he had no choice but to temporarily give up. He decided he would wait for them to shift their attention before quietly slipping away to investigate.
By then, Mouri Kogoro had already called the police. They arrived quickly—led, as usual, by Inspector Megure.
Seeing who was present, Megure sighed with his half-lidded eyes.
"So it's you again, Mouri…"
Mouri happily greeted him and briefly explained the situation, as well as the identity of the victim.
The deceased was Owner Manaka, the man who had purchased the museum and planned to renovate it into a hotel.
Soon, the staff of the museum were escorted in. Upon seeing Manaka's body, they were all visibly shaken.
Natsuyu's gaze lingered on one particular person—the presumed killer, Curator Ochiai.
No wonder he could hang a corpse on the wall, she thought.
Despite facing the police, there was not the slightest hint of panic on his face. He remained calm throughout, only showing brief shock when he first saw Manaka's body.
"Officer," one of the staff said, "every exhibition hall has security cameras. If you check the footage, you might find out who the killer is."
Hearing that there were surveillance cameras, Inspector Megure looked pleasantly surprised. If the crime had been recorded, finding the culprit would be much easier.
Everyone followed him to the monitoring room, where the footage began to play.
At that moment, Conan took advantage of Lisa's attention being on the screen and quietly slipped away from her side, squeezing to the front of the crowd.
Lisa noticed his movement immediately—but chose not to stop him.
She knew very well how obsessed this little detective was with solving mysteries. There was no way he would miss a direct confrontation with the truth. She had stopped him once only because of his outward appearance as a child—and her own identity. But she had no intention of babysitting him every second.
With how openly and recklessly he moves around crime scenes, it's no wonder so many people eventually figured out who he really is.
Turning her focus back to the screen, the footage showed the moments before the victim's death.
Manaka appeared, checked his watch, and seemed to be waiting for someone. He failed to notice as the suit of armor behind him suddenly moved.
The sword came down, slashing his back. Then, with swift movements, the attacker struck him again from the front.
One hand lifted the body; the other drove the sword straight through him, pinning him to the wall.
Just as the figure was about to leave the camera's view, Inspector Megure paused the recording.
"This scene looks a lot like that painting at the crime scene—Divine Punishment," Lisa said calmly.
"Huh! You're right!" someone exclaimed.
Both Mouri and Conan felt the composition looked familiar. They had discovered the body as soon as they entered the hall and hadn't closely examined the surrounding artwork. Now, with Lisa's reminder, they immediately thought of the massive, eye-catching painting nearby.
Mouri concluded that the killer must have chosen this method to imitate that artwork.
Conan had reached the same thought—however…
His eyes slowly shifted toward Lisa.
Even he had been so focused on the corpse that he'd only vaguely noticed the painting. Yet Lisa had instantly connected the murder method to the artwork—and even named the piece.
That wasn't something one could know without deliberately studying it.
Had she realized the connection the moment she saw the scene?
Recalling the victim's unnatural movements after being slashed in the back, Lisa narrowed her eyes slightly.
So that's how it was done…
Then Conan saw Lisa walk over to Natsuyu and whisper something to her. Natsuyu's eyes widened in shock as she turned toward her.
What did she say? Why does Natsuyu look so surprised?
At that moment, Natsuyu stared at Lisa in disbelief.
She already knew the method—and even the evidence.
Natsuyu herself only remembered who the killer was, but she still hadn't pieced together the process or proof. Yet Lisa had figured everything out after seeing the scene and the video only once.
"Insp—Inspector Megure," Natsuyu called out.
"I already know who the culprit is. I also know the method… and the evidence."
Megure and Mouri had just narrowed the suspects to staff members familiar with the museum's interior—based on the earlier "No Entry" sign—when they heard Natsuyu's declaration.
Conan, who had just begun to focus, froze.
W-What?! Already? That fast? We've only watched the video once!
He couldn't believe it.
And more than that—he suspected the truth hadn't come from Natsuyu at all.
He remembered Lisa whispering in her ear.
She must have told her.
Who exactly is Lisa?
Is she really just an ordinary librarian?
Can an ordinary librarian possess such sharp insight and terrifying memory?
