In addition to your already excellent selection of classic adventure games, I would suggest Australian detective adventure game The Dame Was Loaded.
Originally published in 1995/96, it is a detective adventure reminiscent of Tex Murphy, but instead of a sci-fi setting, it uses a classic 1940s noir theme.
The Dame Was Loaded was developed by Beam Software (later to become Krome Studios Melbourne) and published by Philips Interactive Media.
Infogrames or perhaps Atari may hold the current rights to The Dame Was Loaded.
