Adventure Suggestions

I had so much fun running A Quick Trip to France at Origins and Gen Con this year and am already planning on running the game again next year. Now, I just need some suggestions on scenarios/adventures that will fit into a 4 hour slot. Recommendations anyone? I really need to settle on things this coming week if possible.

Achtung! Cthulhu 2d20: Mission Dossier 1 - Behind Enemy Lines or anyone of the individual missions. There’s also Shadows of Atlantis and Forest of Fear (coming out next week).
