I plan to play the 2nd one at some point, but I'd like to play something else in between. Any recommendations for a detective/mystery game? I've played some of the Sherlock Holmes games, though it's been a while, and to be honest I can't remember which ones!
You can check screenshots to see which Sherlock games look familiar.
Other fairly recent detective/mystery games I can think of are
ABC Murders (just released)
Memento Mori 1/2 -- has supernatural elements
Some of the Wadjet Eye games (though most are futuristic)
(link to Wadjet Eye removed until we confirm that Norton's detection of malware on the site is a false alarm)
