Kindaichi Shounen no Jikenbo EP61 - Graveyard Island Murder Case File 2

The group begin to fear the unseen Ghost Soldier and move their camp to an open area and set traps in the jungle around the camp. During the night one of the sound traps is triggered and Hajime and Miyuki see a skeletal Japanese soldier. When they return to camp, they find Namba stabbed to death in his sleeping bag. Hajime also finds all the traps around the camp have been broken. Early the next morning Hajime and Miyuki encounter a mouse which dies from eating poisoned bread, and he later finds clues that indicate that the murderer is someone in their group. That night Iwano asks Hajime to take the first watch and he does, but sets up a dummy of himself in the jungle. The murderer stabs the dummy, then someone tries to strangle Hajime, but they escape. Hajime deduces that the murderer captured Yonemura and used him as a Ghost Soldier decoy to deflect suspicion, and asserts that the culprit is among them.
