[sleightflow]

Very possibly the best game (in my opinion) ever put out during this period. The levels of depth a player can get into are almost endless. I recall spending 48 hours straight, playing the game repeatedly, before finally getting a perfect sleuth score. The type interface makes such a game as this daunting at first, but soon allows for much greater interaction with the plot and players. I beg you not to cheat and read a walk-through... finding the clues yourself is a great thrill. Also, all of the bodies except for two (the first and the last) can be found two places (excluding the third in which all of them can be seen), and if you get to the end, think before you strike. Good luck, and have fun (play it with the lights off and sound up... when Ethel suddenly appears drunk around the estate, you'll have a heart attack.)
The sequel couldn't nearly compare, though it would have had a better shot without the horrible conversation interface.
