No strong impressions on the graphical deduction sheet. Feels a bit like the table I used for the Avalon game but turned up to 11. The whole thing could be done in words, but there’d be so many it would be very difficult to follow. The graphical format makes for an excellent summary.
I’m mostly worried about railroading. Most people aren’t going to have the time to make such a chart, and it’s very easy to just trust the chart to eliminate the unlikely possibilities rather than thinking about them. It could also be an effective tool in the hands of the accomplice if used well, to subtly increase suspicion on others while playing down the true culprit.
For the new information, I’m wondering if that’s pointing us towards a serious injury that leaves blood everywhere. I’m veering in favour of the blender here.
Of course sooner or later the information has to point us at the clue so perhaps this is one of those. Hmm, or does it? If we can conclusively deduce the murder weapon, we just need 4 guesses at the clue to find the right answer.
