Detective Charlie is a cooperative investigation game for children and families. Players take turns rolling a die to move Detective Charlie Holmes around a circle of Witness cards, interviewing townspeople to gather clues. Using the clues, players eliminate suspects one by one from the police station until only the culprit remains. The game includes 6 cases of increasing difficulty, each playable once.
Players take turns clockwise. On your turn:
| Result | Effect |
|---|---|
| 1 or 2 | Move Detective Charlie that many Witness cards in the direction of your choice. Flip the Witness card she stops at; read the account aloud. Optionally clear suspects. |
| Watch | Move the Pocket Watch hand forward 1 hour. End turn. |
| Watch + ? | Move the Watch hand forward 1 hour, then place Detective Charlie in front of any Witness card. Flip and read it. Optionally clear suspects. |
After reading a Witness card, the team may decide to remove one or more Suspect cards from the Police Station based on the clues gathered. Not every witness provides enough info to clear suspects — sometimes you need to combine clues from multiple witnesses.
If Charlie lands on an already-read Witness card you don’t need to revisit, the team may advance the Watch by 1 hour to move to an adjacent Witness card instead.
The game ends when only 1 Suspect remains in the Police Station — they are named the culprit.
Open the Culprit envelope matching your case number. Read the Culprit card together to check if you identified the correct culprit.
| Time on Watch | Result | Points |
|---|---|---|
| 5 o’clock or earlier | Found culprit in time for tea | 5 |
| 6 o’clock | Tea is cold | 4 |
| 7 o’clock | No cookies left | 3 |
| 8-11 o’clock | Station nearly empty | 2 |
| Midnight or later | Everyone fell asleep | 1 |
| Wrong culprit | Wrong lead | 0 |
