Kill the Werewolf

Day 1: On a deserted island, the judge said, 'One of you five is an evil werewolf. Please find him.' The five of us were me, my husband, my son, the hunter, and the witch. My role was a villager. The hunter told everyone: 'My ability is to set traps. I hope to catch the werewolf. As for anyone else who steps on a trap, that's your bad luck.' Night 1: I didn't dare to sleep. Sure enough, my husband choked me in the middle of the night. He was a werewolf! Just when I thought I was going to die, my son jumped out and saved me. My son told me his role was a guardian. My son and I worked together to hunt him down. After my husband died, a wolf's tail appeared behind him. Day 2: Judge: 'He died today. He was a villager who turned into a wolf, but not a werewolf.' We all looked at my husband's body; he had been gnawed beyond recognition. I was very confused. He wasn't a werewolf! And who gnawed him? Night 2: I dreamed I was in a deep pit. There was a white ladder in the pit. I climbed out along the ladder and felt very comfortable, as if I had been redeemed. Day 3: Today he died. I cried uncontrollably looking at my son's body. His body looked soft, but there were no signs of being eaten. The witch pointed at me and said: 'I have a bottle of medicine and a bottle of poison. She was going to die tonight, but I saved her.' Did the witch save me? I remembered feeling very comfortable last night, so it must have been her saving me. Night 3: I actually saw the witch poison the hunter. Did she think the hunter was the werewolf?! Just as I was about to ask what was happening, she suddenly ferociously bit the hunter. She was the werewolf! I ran away terrified! Day 4: Today he died. Before me was the hunter's chewed-up body. The judge said to me and the witch: 'Let's go.' The witch was confused: 'Aren't we looking for the werewolf anymore?' The judge looked at me with a half-smile: 'He's already been found.'
