Solo adventures inside D&D rulebooks

[ShadoWWW]

I wonder if Mentzer's Players Manual and Red Box 4E Player's Book were the only D&D books with solo adventures inside? And I don't mean D&D solo adventure modules like Blizzard Pass, but a solo adventure inside regular D&D rules. Are there some other such book(s)?

The 4e starter set also has one...and references a couple downloadable ones
