The two cards in the extra zip file are also included in my EU Quest Treasure packs, available in the Cards subforum.

Trials, Dark Deeds and Terrors
Hi folks. My first time posting a Quest Pack online! Well, an un-playtested preview anyway.
These quests are pretty basic. I took a leaf out of drathe's book and revised three I originally created in my early teens. You only need the contents of the HeroQuest boxed game to play these, plus the two cards included in the download. They're in European (UK/Australian) format and intended for that ruleset, monochrome maps and all!
'Return to the Catacombs' - A simple kill-the-monster Quest set in the same lair as 'The Trial'.
'A Deal in the Dark' - A Fimir boss has a 'proposition' for the Heroes: they help him retrieve a valuable treasure from the cranky Undead next door, and he'll let them leave alive...
This Quest provides an opportunity for EU players to obtain the Spell Ring (a Quest Treasure adapted from the North American edition of the game)... OR DOES IT?
'Don't Look Back' - A jailbreak Quest in which the Heroes would be wise to choose flight over fight, hurriedly locking doors behind them to slow down the unstoppable tide of alerted monsters.
The three quests are loosely connected by a trio of special characters, but can easily be played as one-offs. I'd say they're best played during the second half of the EU basic questbook or right afterwards.
It's been a while since I had the chance to play HeroQuest, so I haven't had any opportunity to playtest these. EU players, if you feel like giving them a go or just commenting on them, I'd really appreciate it. Constructive criticism is most welcome.

I used Big Bene's Questbook.doc to format them, HeroScribe to make the maps, and Adobe Acrobat to turn them into an (amateurish) PDF.
If anyone wants to adapt them to the North American ruleset, I can provide the text and HeroScribe XMLs.
