It was supposed to be a relaxing vacation for the group of friends as they gathered at the lavish mansion on the private island. Mobin, Ali, Amin, Arian, Anahita, Saber, MohammadMehdi, MohammadHossein, and Amir were looking forward to spending a few days together enjoying each other's company. But the weather had other plans. The typhoon warnings had started before they even boarded the private boat to the island. By the time they arrived, it was too late to turn back. They would have to wait out the storm. As they sat down to dinner on the first night, a mysterious letter appeared at the center of the table. It was sealed with a wax seal bearing the image of a witch riding a broomstick. The letter inside read: "My name is Beatrice, and I am a witch. I have been watching you and I have decided that all of you must die. Before the typhoon passes, I will kill each and every one of you. There is no escape. You have been warned." Everyone was shaken by the letter, but they tried to comfort each other, assuming it was just a sick joke. But then things took a dark turn. One by one, they started dying under impossible circumstances. MohammadHossein was found dead in his locked room with no sign of struggle. Saber was discovered drowned in the indoor pool, again with no sign of struggle. Anahita was found with her throat slit in her locked room. Each death seemed more gruesome than the last. With no one else on the island and perfect examination of corpses not possible due to the ongoing storm, they started turning on each other. Amin, the Iranian nationalist, accused MohammadMehdi, his anti-nationalist rival. Ali blamed Amir, who had always been a loner. And Mobin, who was always sneaky, was suspected by everyone. As the hours ticked by, the group became more and more paranoid, never knowing who would be next. They tried staying in groups but it didn't help. One night, they woke up to find Ali's body in the living room. There was no sign of the murderer. Finally, only two were left: Amin and Arian. Amin turned on Arian, accusing him of being the witch. Arian, in turn, accused Amin. The two started to brawl, and in the chaos, both ended up dead. In the morning, when the storm had finally died down, a rescue team arrived. They found the mansion empty, its inhabitants all dead. The culprit remained unknown, and the mystery remains unsolved. Some believe it was the work of the witch, while others speculate that the culprit was one of the friends all along. When the seagulls cried, none were left alive.
