The Two Deaths of Lord Vale
Reconcile two bodies, two households, and one dead noble.
Mystery campaigns for D&D 5e
D&D murder mystery
A murder mystery your party can actually solve.
Locked rooms, altered manifests, five confessions to one death. The culprit is decided before the first scene, and the evidence is there to be found.
An account is required to play. A card is not.
Most tabletop mysteries fail the same way: the solution drifts to wherever the players happen to look, or arrives as a twist nobody could have seen coming. These are written as fair-play investigations. The killer, the method, and the clues that expose them are fixed before anyone rolls a die.
The AI Dungeon Master holds that solution and plays the suspects around it. Question them, search the scene, compare the testimony, and name the culprit from evidence. The 5e rules handle the checks and the fights the investigation stirs up.

Questions about D&D murder mystery
Frequently asked questions
The practical details before you begin.
Can an AI Dungeon Master run a fair murder mystery?
It can when the answer is not up to the AI. Each of these campaigns carries a hidden solution written in advance: who did it, how, why, and several independent clues that prove it. The Dungeon Master narrates around those facts rather than inventing them, so a theory that fits the evidence is the right one.
How do you run a murder mystery in D&D 5e?
Give the party a closed circle of suspects, a reason nobody can leave, and at least three separate clues pointing at every conclusion they must reach. Let skill checks reveal how much a character notices, never whether the clue exists. These campaigns follow that structure, and the campaign remembers what the party has already found.
Is there a free D&D murder mystery to try?
Yes. The standard library that comes with every account includes a noir mystery for a single investigator. An account is required, a card is not. The free plan covers a limited number of Dungeon Master turns, roughly one session.
How do I get the murder mystery pack?
The pack is a one-time purchase that stays in your library permanently. Buying it needs a plan with unlimited turns, since an investigation runs longer than the free plan's turn limit. Legendary members receive a pack credit every month that can be spent on it.
Can a group investigate together?
Yes, up to six players, and each case lists the party size it was written for. The host invites friends with a link and they play free, and the whole party shares one record of what has been uncovered.
