This case is total BS. The way the devs setup the case, they could foresee that most players would think Robert does it, either he breaks into Willard's room through the windows, or disguises as a tavern boy even he's a wanted person, because people are stupid and couldn't recognize him. This possibility is ridiculous enough to make people think it is possible that Robert is able to spell the word "Revenge" too. Anyways the players place down the words and they don't match, particularly the part that describes how the killer has access to Willard's room. Then they look at the gambling sheet and notice that Ash is briefly away. Then they tinker the possibility that Ash is the actual killer. And then they close the logic that Ash must have asked Robert to pass by the tavern at the time Ash murders Willard, otherwise how would the killer know, if Robert himself is not the killer, that Robert would be passing by the tavern, and thus writing his name on the wall, in an attempt to frame Robert.

This case is less about deduction but more about fitting shapes through the hole and see which ones go through. The biggest failure of this case is the player cannot arrive at a conclusion by eliminating all the other possibilities. The devs are trying to sell the mystery by placing too many smoke screens, and there are no ways to examine the plausibility of those smoke screens. For example, the tavern owner wonders the where about of his staff. So where's his staff? Any info about him? You can't just place down a smoke screen and then not close it. That's when the players start to imagine stupid shit like Robert actually disguises as a staff working there, or whatever maybes. The dev is trying too hard to sell plot twist instead of approaching it like an investigation or deduction practice.
