Modular Narrative System for Detective Storytelling, 2026
MURDEX
MURDEX is an original tool for developing detective stories.

A set of 176 cards structured into 15 categories helps construct logically coherent narratives — from the crime event itself to psychological motivation and investigation mechanics.

The project is aimed at writers, screenwriters, narrative designers, and game designers.
At the core of MURDEX is the idea of a detective story as a system of interconnected elements.

Each category in the deck has its own color code and internal variability. The cards allow you to design a story modularly by combining elements and testing them for logical consistency.

Combining cards builds the foundation of the conflict and then allows you to gradually complicate the structure of the story.
