Narrative Synthesis

CASE FILE: #992-B // THE MISSING DIAMOND

Lesson Goal: Learn to read multiple sources of information, compare them, and find the logical truth.

Putting the Pieces Together

In real life, information doesn't always come in one neat paragraph. You might receive a text message, read an official document, and see a photograph all in the same day.

Narrative Synthesis is the skill of taking these different, disconnected pieces of information and combining them to understand the full story. Detectives do this every day when they build an evidence board. They look for contradictions—places where one piece of evidence proves another piece is a lie.

Go to the next tab to learn your detective vocabulary, then examine the Evidence Board in the Practice tab to solve the crime!
