I love this Mystery so much!
I created some fan content to help run the mystery; it is basically cards with a picture and the name of the Victim and each of the Suspects. In my Brindlewood Bay games, I use shared whiteboard tool from Google called Jamboard, and I can create a frame into which I drop these cards. After I do that, they can manipulate these cards, move them around, jot clues or notes onto sticky notes within Jamboard, draw on the Jamboard with a marker, etc. I'll attach a photo of what it looks like.
If others want to check out my fan content, I created a folder which is publicly accessible through this link: https://drive.google.com/drive/folders/1DYjp0R_xd5Gl-m4srYi5qSpa973zhjP6?usp=sha...
Happy gaming! - Brian
