Cleaning up some old files on my computer, I ran across these two adventures I had written and submitted to the RPGA for the annual GenCon competition (back in the day).
The first was an adventure for TSRs Amazing Engine system. Symbolic Apparatus is based in London, but will take the investigators out to the ocean. I won second place with this adventure. A PDF of the original submitted to the RPGA can be found here.
After winning second place, I felt I should try and submit an actual Dungeons & Dragons adventure the next year. Mirrored Possibilities takes a small group of beginning adventurers to a smudge of a village and from there on to an abandoned wizards tower. I won second place with this adventure.
