Crime & Mystery
The useful clue is often the habit nobody thought worth noticing.
A victim’s routine can do more work than a dramatic object ever will. The same mug in the same sink, the same walk, the same unanswered message at the same hour. Then one day the pattern stops, and that absence starts looking less like accident and more like design.
Crime fiction likes a loud clue. Real people leave quieter ones. Writers who use those small repetitions well usually end up with a better mystery, and a more convincing dead person, which is a grim thing to improve but there it is.

Routine is useful, but only if the writer knows what to do with it. A repeated detail on its own can become wallpaper very quickly. What matters is whether the pattern means something to the character before it means something to the reader. Otherwise you just get a neat little clue sitting there waiting to be admired, which is rarely how real life works.
