The first two you listed are for basic/expert, designated M1, and M2, respectively. The other basic/expert solo adventures were:mrcasey said:Here are the the few of which I'm aware:
Blizzard Pass
Maze of the Riddling Minotaur
Midnight on Dagger Alley
Also, in the old Dungeon magazines, solo adventures appear every once in a while. My favorite is a solo 10th level thief adventure. I believe the title is something like Whitefang. It has the feel of a choose you own adventure book, but the writing is sharp and clever.
Alas, I can't tell you where to find these works. As they're long out of print, you might try Ebay.
