Oh wow, this is awesome! Thanks monster, for years I wondered what the game was but just now was prompted to look for it online.
I had a detective game when I was a kid, where I actually kept records of everything, who was the culprit how the clues worked out. Documenting that like I did, it's not surprising I landed in a field where it's all documentation all the time. I was pretty young as I recall, when I had the game. I tried to google it and I'm sure this was the game! What memories. I played this one by myself a lot. I wish I still had it.
