The Murder Hotel

Feel free to call me Gastfenger. I'm the demonic hotelier, at your service. Oh, you want to leave already? How amusing. Nobody leaves this place unless I allow it. How about you solve 4 murder cases. Easy, you say? There's a twist to them. It is I who murders my own guests. And it's your task to investigate and successfully blame one of the other guests as the culprit. Defeat your rival and convince the Demon Council to win a case. Lose just once, and you'll stay here, forever! Dare challenge me?
