I went to
http://www.adventurecompanygames.com/tac/index.html
scrolled down and clicked on the link for Still Life.
Up pops this box saying
"To view Mature content, please verify your age:"
After putting a made-up birthday into it, I got the page to come up.
What a disappointment! There's one "maybe naked but you can't really see" dead body in a bathtub and one of the screenshots has the F word written on a wall. Not my idea of "Mature content" at all.
