The plain, light-colored belt around Tendo Haruka's waist only passed through the belt loops on the left and right sides.
The belt loop in the middle of her lower back was pressed beneath the belt instead of having the belt threaded through it.
Hearing Yoshida Ayumi's words, Tendo Haruka instinctively reached back to feel it. The moment she touched that incorrectly threaded section of belt, her expression changed drastically.
"The killer's flaw lies in their clothing..." Officer Sato recalled what Jiang Xia had said earlier. And based on that...
She looked at Tendo Haruka. "You're the killer?"
"Of course not!" Tendo Haruka hurriedly said. "I overslept today and left in a rush. I was flustered and accidentally fastened my belt wrong... Everyone makes little mistakes like that, don't they? Why does that make me the killer?"
Hearing this, Jiang Xia turned to look at Professor Agasa and held out his hand.
Professor Agasa looked at Jiang Xia, then lowered his head to look at Jiang Xia's hand. "...?"
What do you want? How am I supposed to guess? I'm just an ordinary scientist who can't deduce anything!
Fortunately, Conan had thought of it too. He hurriedly used Jiang Xia's voice: "Didn't we take quite a few photos while playing at the campsite this afternoon?"
"Oh! You want the Camera." Professor Agasa hurriedly dug out the Camera and placed it in Jiang Xia's hand.
Jiang Xia looked down at the Camera, fiddled with it for a while with a few beeps, then opened one of the photos and turned it toward the others.
—The photo showed them setting up the tents.
Tendo Haruka was crouched on the ground, holding nails and a Hammer as she drove in tent stakes, while Yoshida Ayumi stood across from her and helped hold the nails.
