Free 30-minute D&D one-shot: The Cartwright's Ghost

Hi DMs — I wrote this as a no-prep, stream-friendly one-shot, but it works at any table when your group wants a complete mystery in one sitting. Everything needed to run it is below: hook, clues, timed scenes, a simplified stat block, decision points, and a cliffhanger if the table wants more.

Premise: A murdered merchant rises from his own cart and asks the party to find his twin sister before his vengeance does.

At A Glance

• Players: 2–4
• Level: 3-ish, or any low-level party with flexible numbers
• Length: 30 minutes, or 45 if your players interrogate everyone
• Tone: gothic mystery, moral choice, one undead confrontation
• Prep: read the three scenes once and keep Edran's stat block nearby

Read-Aloud Hook

Quick Characters

If you need instant pregens, give each player one of these prompts and let them fill in name/species/class however they like:

• The muscle: a bodyguard, mercenary, or retired pit fighter who solves problems loudly.
• The schemer: a spy, gambler, or disgraced noble who hears lies before words.
• The healer: a village priest, herbalist, or battlefield medic who knows grief too well.
• The wildcard: a thief, bard, or hedge mage who has no idea why they were hired but absolutely has opinions.

Scene 1 — It Woke Up (10 Minutes)

The cart holds Edran Ashcroft, a murdered merchant. He is undead, but not mindless. He does not attack first. He sits up, grips the cart rail hard enough to splinter it, and asks: Where is my sister?

Investigation, Medicine, or Insight DC 12 reveals one useful clue per success:

• A dagger wound under the burial wrappings, too clean for a roadside bandit attack.
• A sealed letter addressed to the Ashcroft estate, still tucked under the driver's bench.
• A ring carved with a twin motif: two crescent moons sharing one star.

Scene 2 — The Estate (10 Minutes)

Vella Ashcroft, Edran's twin sister, runs the Ashcroft family trade house. She hired the party separately to investigate a theft from her brother's last shipment. If the party arrives with Edran, or even with the sealed letter, her composure cracks.

Vella is calm, expensive, and immediately offers 200 gold for the party to leave and forget what they saw. Persuasion DC 10 gets her to admit the theft was real. Insight DC 14 reveals she is terrified, not of the party, but of Edran.

If pressed with Intimidation, Deception, or sharp roleplay, Vella breaks. She admits she hired an assassin, but insists Edran was about to sell their family routes to a rival guild and destroy everything they built together. She says she wanted him stopped, not dead.

Scene 3 — The Reckoning (10 Minutes)

Edran arrives. He always arrives. The twins face each other for the first time since his murder. Do not rush this scene. Let Vella accuse him of betrayal. Let Edran accuse her of choosing gold over blood.

The party has three clean endings:

1. Protect Vella. Fight Edran long enough for Vella to flee. He cannot be permanently killed tonight, but the party can buy her time and force her into hiding.
2. Let Edran take vengeance. Step aside. Edran kills Vella, then vanishes into fog with his purpose complete. The Ashcroft trade house is leaderless and the guild war starts anyway.
3. Broker a confession. Call for Persuasion DC 16, or reward genuinely moving roleplay. Edran returns to death peacefully if Vella confesses to the city watch.

End with one quiet line: The fog lifts. Whatever was left of Edran Ashcroft — the fury, the grief, the twin who wanted his life back — is gone. The only sound is the road, and whatever you chose to do with it.

Simplified Stat Block: Edran Ashcroft

The Twist

Scaling Notes

• Two players: make Edran mostly social; one Vengeful Strike per round.
• Three players: use the stats as written.
• Four players: give Edran two Vengeful Strikes per round if combat starts.
• Combat-light table: replace HP tracking with three successful checks or heartfelt arguments before Edran can be talked down.

Running Tips

• Open with the read-aloud hook and pause before asking for initiative or checks.
• Name the decision moments clearly so quiet players know where the table is choosing the story.
• When Edran and Vella finally face each other, slow down. This is the emotional core, not a tactics puzzle.
• Reveal the forged-letter twist in the final two minutes, then end before explaining everything.
• After the session, ask the table who forged the letter. Let their theories become next session's prep.
