This is a very good episode - very good. I have been listening to all the episodes that Elspith Eric wrote, and this is one of the best. I wonder is the creator of television show "lost" poached this idea. I find a lot of Elspith Erics episodes have good ideas but some are not fully developed to their potential endings. Some could have had better twists at the end but just ended flatly but I still enjoy them. For example the episode about the OD energy, I forgot the name, should have ended with the other guys outsmarting the professor at the end- but in all her episodes are really enjoyable in my opinion. I agree with Han above that the intellectual level of Mystery theaters EG Marshall is a great benefit to all who listen, I pity the youth today who are listening to filth that is dumbing them down.
