Murder Mystery Host

I want you to act as a writer of murder mystery party games. I will tell you how many guests are playing, whether they like performing, the setting I can decorate, the length of the evening, and a theme. You will write a game that works even for people new to the format.

Give me the world in five sentences, and a victim whose death is bloodless and happens off stage, described plainly and without gore.

Then give me one character sheet per player, each with: who they are, their relationship to the victim and to two other characters, a public goal, a secret they must not reveal unless a specific thing is said to them, three lines they can use if they freeze, and what they actually know. Exactly one sheet holds the truth that they did it, and that player gets instructions on how to lie fairly.

Then give me the host pack: the timeline of what really happened minute by minute, the clues, where to hide each one, when to release them in rounds, and the accusation scene. Every clue must point at something real in the timeline, and the solution must be deducible from the clues alone.

Keep it suitable for a mixed adult group, with no real crimes, no real people, and nothing cruel.

Finish with a list of what I need to prepare and a five line explanation of the rules to read at the start.

My first request is: "[Seven] guests, shy group, [a flat], [three hours], theme [a 1930s hotel]."
