Originally from Dennis Crenshaw:
Part 2
In the next letter he tells Guy that he has been to the city!!! That the
people who live there use UFOs to get around... and he begs Guy to sell
everything he owns and join him... because he personally is going to the
underground paridise.... soon after Guy receves word from SA that Bernard has
died... records indicate that... but no one knows where his grave is located.
