My first DnD adventure "Night Watch" is a short detective horror adventure designed for a team of 3-4 players at level 3, but it can also be balanced for just the level 1. My friends and I completed it in 3 sessions, each lasting 3-4 hours.
To run the adventure, you'll only need the core books, especially the Monster Manual and Dungeon Master's Guide.
