International Dungeon Designs produced at least 2 dungeons. One was Escape from the Minotaur's Lair and the other is The Bane of Bryreville. Laurence D. Swanson was the principle designer (perhaps the only one in the company too). The inside of EftML boosts how 'Mr. Swanson has created more than 30 dungeons destined for print'. Swanson is also listed as esq and Master Designer...
As rare as EftML is we think Bane of Bryreville might be even more so.

-- Escape from the Minotaur Lair -
"Being the ambitious group of adventurers that you are, you quickly answer the summons of the Lord Baldwin of Casbar. He informs you that one of his daughter's hand maidens has vanished. He is offering ten thousand gold coins for her swift recovery. He suspects that she was kidnapped by an evil Minotaur..." -Prelude to the scenario of the Escape From the Minotaur's Lair. By looking at the cover, I am not sure the Lord's daughter's hand maiden is in a hurry to get home!

-- The Bane of Bryreville -
Also states on the cover that it is Abode from the Father Tourney, I suppose this is additional to the title? Goblins are ambushing caravans entering Bryreville, it is up to the adventurers to find out who is behind the attacks.
