Hello, we need your help. You are a cop as we know. Yes, it is not duty time now but we would like to request you to help. Our friend who had gone inside the ruined house has not returned as yet. We are very worried about him. He is probably stuck in one of the rooms in the house. Only a very smart person can go inside the house to rescue our friend. We hope that there will be some clues and items that you may have to find and use very intelligently. We really do not think that we need to teach you anything beyond this.
