So, I did another playthrough with the browser version and I have to admit things made a lot more sense^^
That being said, it felt like there was a bit too much information to be gathered and pieced together. But maybe only fraction of it is necessary to guess the murderer ?
Here's what I found out (spoilers ahead for anyone else reading) :
-The body was dragged in the garden, it seems the murder happened in the study, near the phone ? (there is a pool of blood there)
- I could not make a complete timeline of events but there was an interview with the journalist, then Mr. Hamilton went to have a private discussion with the businessman, then he handed an enveloppe to the butler to deliver to the businessman then I'm not sure. I think he left the house at some point ?
- Basically everyone had a motive to kill him (exept maybe the journalist)
- I'm pretty sure the wife and / or the cook killed him because they both lied or were "confused" about where the wife was when they first heard about the murder. Also, I found a recipe for 'poisoned cake' written by the wife, that feels like a strong clue ^^
Like I said in my first message, I really like the concept. Now I just feel like the amount of information, characters and details to keep track of is a bit overwhelming. I'm not sure how / if it could be simplified though. Having more details during the briefing at the start (the body was discovered at X by Y at Z hours...) would also help a lot.
So I'm mostly of the same opinion of Wandering Peak but I'm honestly curious what other people would make of it.
