"Murder One!" by Dean Mackie, Peter J. Lear, Graham Richards (1985)

This is an game modified to work on the TRS-80 Micro Color Computer ("MC-10") using Micro Color BASIC from the author's published source code in the TRS-80 Colour Computer Programmer's Handbook/What Else You Can Do With Your TRS-80 (Hayes Publishing Ltd. Burlington, Ontario, 1985).

Interesting ... obviously it's Clue adjacent, but without the running around. Looks like this could be a multi-player game with the players taking turns.

Yes, it's multiplayer. Any number can simply take a turn. If they eventually guess wrong, a message is displayed saying that they are "out of the game."

Everyone is supposed to keep their own information card, but I added one (the help prompt) that keeps track of the basic info of clues (X) and who has or does not have info (?)
