Dossier Noir
Solve the cold case files
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Five cold cases. No answers. Until now. Read the evidence, spot the contradictions and solve the case – first file free.
Dossier Noir puts a real cold case file in your hands. Statements, letters, logbooks, photos and sketches – everything you need is in the file. Read carefully, take notes, mark suspects and find the contradictions.
HOW IT WORKS

• Study the evidence: statements, reports, letters, sketches
• Answer the investigation questions in 3 stages – new evidence is released after each stage
• Stuck? Up to 3 hints per stage
• Solve the case and read the full solution
