Murder Mystery Suspect Board Template

Running a mystery scenario is one of the most rewarding — and most complex — things a Dungeon Master can do. Keeping track of suspects, motives, alibis, and hidden connections across multiple sessions is genuinely hard without a visual aid. The Mystery Web template gives you a pre-built relationship map that you can customize for any whodunit, crime investigation, or noir campaign.
