Broken Sword 5: The Serpent's Curse (2013)

The in-game hint icon offers clues about the current predicament, with further requests giving more detail on the same subject. That is a useful way to untangle a longer investigation without opening a page containing later story answers. Leave hints enabled in the menu, and choose the complete PC game with both episodes. Some clues become direct quite quickly, so read one before requesting another. I would choose Reforged first for its additional automatic Story Mode assistance; this has its own separate mystery.
