Important note: The riddle leading to the hostage's location no longer works correctly, because after this quest was written one more entry was added to Ascii Sector's list of planets. Add +1 to the count to get the correct solution.
Note 2: At the end of the quest under Linux I got an error message "Error: quests/quests/lady1.qst - File not found". I don't know if this is specific to Linux, or this quest in particular, or both. I could work around it by creating a symlink in quests/ pointing to the current directory, like this:
cd quests ln -s . quests
