How to track clues in a mystery RPG campaign
Keep the truth, the evidence the players have discovered, and their theories separate so a guess never quietly becomes a confirmed fact.
The short answer. Write down what really happened, then keep each clue separate from your explanation of it. Record exactly what reached the table and label player theories as theories. A clue note should let you find the evidence and check how the party learned it.
A player asks, "Was the receipt dated before the bell disappeared?" You know who took the bell, but you cannot remember whether you mentioned the date when they found the receipt last week. Good mystery notes preserve that difference.
Start with what really happened
Imagine Bellwater's ceremonial bell disappears on the night before a festival. Your private explanation is that the steward moved it to stop a dangerous ritual. The miller lent him a cart without knowing what it was for.
Write that down, including the timing. Then think about what their actions would leave behind: a cart receipt, tracks outside the tower, and a witness who saw the steward out late.
Give the group more than one way to make an important discovery. If they never inspect the tracks, the receipt or the witness could still give them someone to question.
Keep the clue and your explanation separate
Here is a GM note for the receipt. It separates what is on the paper from what you know and what you told the players:
- Clue: Cart receipt found in the bell tower's stove. Partly burned; the miller's seal is intact.
- Visible detail: Dated the day before the bell disappeared. The recipient's name burned away.
- GM explanation: The steward borrowed the cart and tried to destroy the receipt.
- Session 3: The party searched the stove. I described the seal and burned edge. Nobody asked about the date, and I did not mention it.
The date is visible on the paper, but the players have not heard it yet. When they ask next session, you can check your notes and answer.
"The miller's seal appears on the receipt" is evidence. "The miller stole the bell" is an interpretation. Keep both if the party suspects him, but label the second as their theory. Otherwise, a hasty recap can turn a guess into something everyone remembers as confirmed.
For spoken clues, write who said what. "A witness saw the steward near the tower" is different from "The steward was at the tower." The witness might be mistaken, lying, or leaving something out.
Give suspects lives beyond the case
The miller is innocent of stealing the bell. That does not mean he has nothing to hide. Perhaps he is lending out the cart despite an agreement with his business partner, and he is embarrassed to admit it.
On his page, jot down what he knows, what he says, and why those accounts differ. Add how he feels about being accused. If he is angry enough to slam the door, you have a starting point for the conversation when the party knocks.
Build suspects with useful NPC notes
Let the players be wrong for a while
Suppose Nessa's player says, "I think the miller stole it to embarrass the steward." Record whose theory that is. You do not need to correct it just because you know the answer.
If the party questions the miller, he can tell them when he lent the cart and who collected it. They might believe him, catch him hiding the business arrangement, or leave more suspicious than before. Let them decide what his account means.
A shared evidence list helps the group revisit what it found. Individual theories can go in player journals, where "Nessa thinks..." stays a character's perspective.
Keep theories in a player campaign journal
When you recap, use the same care. Say, "You found a receipt with the miller's seal, and you are suspicious of him." That preserves the party's reasoning without announcing a verdict.
Common questions
What should I do if the investigation stalls?
First check whether the players have the information you think they have. If a prepared detail never reached them, make it available. If they are overlooking something their characters would remember, remind them. If they have exhausted their leads, introduce another source, such as the cart driver or a tower attendant. They still decide which lead to follow and what to make of it.
Keeping the bell mystery in Storywright
You could create an item entry for the receipt in Storywright and link it to the miller and bell tower. When the party finds it, share a description of the seal and burned edge you told them about. Put the steward's involvement in GM notes, and record the discovery in that session's notes.
Next session, check the receipt's entry for the evidence and the session notes for how the party found it.
