Great selection. "The Ninth Volume" remains one of my favorite RMT's; it combines a fun, interesting story with good performances. I love the performance by the actor who portrayed Sharkey (or whatever his name was) who lied when asked to confirm the scientist's claims about the modern dwelling below the earth. I laughed when Sharkey said he didn't recognize half of the names the geologist read out as authors of various books in the library.

As for the ending, I took it to mean that the two scientists died after the house disintegrated; I don't see how they could have escaped, but I hope I am wrong!

This episode occurred in the far flung future of....1998. I guess that means the end is near.
