Overview

Historical Mystery: Death at the Ball is a cooperative deduction card game where players investigate the poisoning of a French nobleman at a ball. Players have exactly 24 moves to interrogate suspects, examine crime scenes, and gather evidence. After the investigation phase, players answer a series of questions about the case to determine how well they solved the mystery. The game emphasizes narrative storytelling with unexpected twists while leaving all major decisions to the players.

Components

• 56 Cards (suspect cards, evidence cards, location cards, event cards)
• 1 Rulebook
• Case questions sheet

Setup

1. Sort the cards as described in the rulebook.
2. Lay out the initial crime scene cards.
3. Each player receives their starting hand or position as directed.
4. Set the move counter to 24.

Turn Structure

Players take turns performing investigation actions. Each action costs one move from the 24-move budget.

On your turn:

1. Choose an investigation action (interrogate, examine, or visit a location).
2. Resolve the action by reading the relevant card(s).
3. Reduce the move counter by 1.
4. Discuss findings with other players.

Actions

Interrogate

• Visit a suspect’s household and question them.
• Draw and read the corresponding suspect card to gain information.
• Costs 1 move.

Examine Evidence

• Inspect a piece of physical evidence or a location detail.
• Read the evidence card for clues.
• Costs 1 move.

Visit Location

• Travel to a specific location tied to the investigation.
• Reveal new cards or suspects.
• Costs 1 move.

Scoring / Victory Conditions

After all 24 moves are used (or players choose to stop early):

1. Players collectively answer a series of case questions about the mystery.
2. Questions cover: the culprit, the motive, the method, and key plot details.
3. The more questions answered correctly, the better the group’s score.
4. A perfect score means solving the case completely.

Special Rules & Edge Cases

• Cooperative play: All players work together and share information openly.
• 24-move limit: Players must budget their moves carefully — investigating everything is impossible.
• No replaying: Once all cards have been read, the mystery is solved or failed. The game is designed for a single play-through per case.
• Solo mode: Can be played by a single player controlling all investigation moves.
• Historical setting: The mystery is set in a historical period with period-appropriate characters and settings.
• Card order matters: Some cards reference others; reading them in different orders may reveal different aspects of the story.
